Viola by Antonio Stradivari, Cremona, 1690, Fulton, ex-Baird, Tuscan-Medici by Antonio Stradivari
Artist
Antonio Stradivari
Date
1690
Medium
Spruce top; two-piece back, ribs and scroll of quarter-cut maple; oil varnish over gesso ground
Dimensions
Length of back 41.4 cm; upper bouts 18.7 cm; middle bouts 13.1 cm; lower bouts 24.3 cm; back arching rises to 19.5 mm, top arching to 18.7 mm. A contralto (alto-register) viola.
Inscriptions
Inside the top, treble upper bout, in pen: 'The Medici Stradivari / A.H. June 1913', left by Alfred Hill. Original Stradivari label retained inside the instrument; its exact wording was not published in the sources consulted.
Attribution
accepted
Accepted as an autograph Stradivari on the basis of a retained original label, an interior inscription left by Alfred Hill of W. E. Hill and Sons in June 1913 identifying it as the Medici viola, a written certificate of authenticity issued by W. E. Hill and Sons on 2 February 1957, and the Library of Congress's own organological study, which found high barrel-form arching and top-wood dendrochronology consistent with Stradivari's output of the 1690s. No modern connoisseurship dispute over the attribution was found in the sources consulted.

Period
Italian, seventeenth century, Cremonese school

A contralto viola built by Antonio Stradivari in Cremona in 1690 for the Florentine court of Ferdinando de' Medici, one half of a matched pair of violas that was split up by the late eighteenth century, its tenor sibling staying in Florence while this one crossed to England, then to New York, then through the hands of a department-store heir whose father died on the Titanic, and finally to a Buffalo music professor whose 1957 authentication certificate from W. E. Hill and Sons remains its clearest formal proof of authorship.

It reached the Library of Congress in 1977, not as a gift but as a private loan from the professor's widow, and stayed a loan, played annually in the Library's own Stradivari memorial concert and the subject of a Grammy-winning concerto, for forty-eight years. Only in April 2025 did a 30 million dollar gift, split between a Seattle collecting couple and the original owning family, convert the loan into outright ownership and give the instrument its present name: the Fulton, ex-Baird, Tuscan-Medici.

No forgery dispute and no theft attaches to this instrument. Its real complication is custodial: for nearly half a century, one of the instruments the public associated with the Library of Congress did not actually belong to it.

The artist

Italian (Cremonese) · 1644-1737

Antonio Stradivari

Antonio Stradivari worked in Cremona for roughly seven decades and left no treatise explaining his methods; almost everything known about his working practice is reconstructed from the surviving instruments themselves; through dendrochronology, arching measurement, varnish analysis and connoisseurship built up over more than a century, the same kind of evidence that authenticates this viola. Around six hundred and fifty of his instruments are thought to survive out of a much larger original output, and only a small number of violas are among them, which is part of why this instrument's condition and paper trail matter.

Dates and place
Born in or near Cremona around 1644; died there on 18 December 1737. The Library of Congress has held an Antonio Stradivari Memorial Concert every year since 1936 on the anniversary of his death, a tradition it describes as the longest-running commemoration of the maker by any institution.9
Training
Generally thought to have trained under Nicolo Amati, the leading Cremonese maker of the early seventeenth century, whose instruments are described as having a sweet, mellow tone against which Stradivari's own early work is often compared.8
The four periods
Stradivari's output is conventionally divided into an early period through the 1690s working in the Amati manner; an experimental period around 1690 to 1700, when he lengthened the body and narrowed the width of his instruments for a more concentrated, projecting sound, exactly the transition this 1690 viola sits at the start of; the 'golden period' of 1700 to the 1720s, broader and richer in tone; and a late period in the 1730s, producing a darker voice.8
Latinized labels
Like his contemporary Giuseppe Guarneri, Stradivari followed the period custom of Latinizing his name on his printed labels, to Antonius Stradivarius, which is why the instruments are commonly called Stradivarius violins in English even though the maker's own name was Stradivari.8
Violas are rare in his output
Of Stradivari's surviving instruments, violas are the smallest group by a wide margin; sources consulted give figures of roughly ten to a dozen surviving examples, and this instrument is counted among them by every source that discusses it.710
A named patron network
This viola was made for the court of Ferdinando de' Medici, Grand Prince of Tuscany, an active patron who two years earlier had hired Bartolomeo Cristofori, whose work for Ferdinando led to the invention of the piano around 1700. Stradivari's viola and Cristofori's first pianoforte both trace to the same Florentine court within a decade of each other.45
We cannot replicate the art form. The best works of Stradivari and Guarneri have never been surpassed. They were masters at the beginning of the art.Geoffrey Fushi, president of the Stradivari Society and a founding partner of Bein and Fushi Rare Violins, speaking at the Library of Congress in December 1998; he had by his own account played between 120 and 130 Stradivari instruments

What it is

A contralto viola, 41.4 cm at the back, built by Antonio Stradivari in Cremona in 1690. It carries a spruce top and a two-piece maple back with matching ribs and scroll, under an oil varnish, and its arching is high and barrel-shaped, a form Stradivari was using in this exact decade before he lengthened and narrowed his instruments in the pattern changes of the following ten years.

It is one of a very small surviving group. Sources consulted give two different counts for that group: the Library of Congress and the Cozio Archive both describe it as one of roughly ten surviving Stradivari violas, while a 2017 report on the Library's own collection put the number at around a dozen. Both figures come from named, citable sources, and this record has not been able to reconcile them; the discrepancy is left as a finding rather than resolved by guesswork.

A gift for the grand prince

The viola was made as part of what later became known as the Medici quintet: two violins, a cello, and eventually two violas, a tenor and this contralto. The commission is associated with Bartolomeo Ariberti, a nobleman of Cremona, and with Ferdinando de' Medici, Grand Prince of Tuscany, the eldest son of Grand Duke Cosimo III and the family's principal patron of music, sometimes called in his own lifetime the Orpheus of princes.

Ferdinando's patronage had a second, more famous consequence. In 1688, two years before this viola was made, he hired the harpsichord maker Bartolomeo Cristofori as keeper of his musical instruments; Cristofori built the first pianoforte for Ferdinando around 1700. The Medici Stradivaris and the invention of the piano both trace back to the same court and the same patron, though this record makes no claim of any direct link beyond that shared origin.

An older cataloging tradition, reflected in the title of W. E. Hill and Sons' 1891 monograph on the sibling violin, names the recipient as Cosimo de' Medici, Grand Duke of Tuscany, rather than his son Ferdinando. This record follows the more specific and more recent sourcing, which credits Ferdinando as the musical patron of the commission, and notes the older attribution as a labeling variant rather than a competing claim.

The quintet comes apart

The instruments did not stay together. The set was broken up at an unrecorded date, and the two violas were separated from each other by the late eighteenth century: the tenor viola remained in Florence and is now held by the city's Galleria dell'Accademia, through the Conservatorio Luigi Cherubini, while this contralto viola left Italy.

According to W. E. Hill and Sons' 1902 monograph on the group, the contralto arrived in England with the last descendant of the noble Gianfigliazzi family of Florence, and in 1803 it was sold to an Englishman resident there. The next hundred years took it through France and back to England before it crossed the Atlantic.

A private English chain

The nineteenth-century ownership record, reconstructed from the Betts notebook and preserved in the Cozio Archive, runs from Bright and Jones to Alexander Glennie, then to Glennie's son-in-law F. F. de Rougemont, then to Avery Tyrell, who inherited it from his father Edward. None of these transfers carries a firm date in the sources consulted, and this record does not invent one; the chain is treated as documented in sequence but undated in detail.

W. E. Hill and Sons acquired the viola from the Tyrell heirs in 1913. Alfred Hill inscribed the inside of the top in pen that June, identifying it as the Medici Stradivari, and the firm judged it, in its own words, one of the finest of the ten existing examples of Stradivari's viola work, its preservation as remarkable as the beauty of its appearance. The Hills sold it to the collector Richard Bennett in 1913 or 1914, later reacquired it, and sold it again through the Rudolph Wurlitzer Company of New York.

A Straus, and a family already marked

The Wurlitzer firm sold the viola to Herbert N. Straus. The Library of Congress's own account dates the sale to 1925; other sources consulted, following the Wurlitzer and Hill chain, place it in 1924. This record carries both dates rather than choosing between them.

Straus was an amateur musician and a son of Isidor and Ida Straus, co-owners of R. H. Macy and Company. Isidor Straus died aboard the Titanic on 15 April 1912, thirteen years before his son's name enters this instrument's record. Herbert Straus's own motive for the purchase is not established in the sources consulted; it has been described as completing a personal collection of Cremonese instruments, without further detail.

Cameron Baird's certificate

Cameron Baird, a violist who founded and chaired the music department at the State University of New York at Buffalo, bought the viola from the Straus estate in 1957. On 2 February 1957, W. E. Hill and Sons issued a written certificate confirming Stradivari's authorship, the clearest single point of formal authentication this instrument carries.

During Baird's ownership the viola did not sit idle. It was loaned for worldwide performance to Boris Kroyt of the Budapest String Quartet, and Kroyt's quartet colleague Alexander Schneider also played it frequently. Baird died in 1960, and the instrument passed to his widow, Jane Baird.

Forty-eight years a guest

In 1977, Jane Baird placed the viola on long-term loan with the Library of Congress. This is the complication that separates this instrument's history from the five Stradivaris that Gertrude Clarke Whittall gave the Library outright in 1935 and 1936, the 'Betts', 'Ward' and 'Castelbarco' violins, the 'Cassavetti' viola and the 'Castelbarco' cello, each bound by Whittall's own terms to be played regularly and never removed from the building.

The Tuscan-Medici viola carried no such deed. For forty-eight years it was, technically, a guest: cataloged, photographed, played in the Library's own Antonio Stradivari Memorial Concert (an unbroken annual tradition since 1936), and displayed in May 2018 alongside the Whittall instruments and the Nippon Music Foundation's Paganini Quartet of Stradivaris for what the Library called a record-setting gathering of ten instruments by the maker, including three of his violas. Ownership, throughout, remained with a private family and, from at least the 1980s, with the Baird family's Tuscan Corporation. A change in the family's intentions, or a change in the corporation's fortunes, could at any point in those forty-eight years have taken the instrument out of the building for good. That it did not is a matter of the family's choice, not of any obligation recorded in the sources consulted.

A concerto and a Grammy, while still on loan

In 2015, still on loan and not yet owned by the Library, the viola was the subject of a new concerto. The Library co-commissioned the composer Jennifer Higdon, with support from the Baird and Medvickis families, to write a work for it; the violist Roberto Diaz, president of the Curtis Institute of Music, premiered the concerto at the Library. The composition won two Grammy Awards in 2018, for Best Contemporary Classical Composition and Best Classical Compendium. Both the manuscript and a recording of the premiere remain in the Library's collections.

The gift, finally

The loan became a gift on 30 April 2025. David and Amy Fulton contributed 20 million dollars in cash, and the Baird family, through the Tuscan Corporation, contributed the remaining value of the instrument, assessed at 30 million dollars in total, as an in-kind gift; in giving up that 10 million dollars in value rather than realizing it in a sale, the family's contribution functioned as a bargain-sale donation. The exact mechanics of how the Fultons' cash and the Bairds' in-kind contribution were structured and administered, and whether either side sought or received a charitable deduction, are not stated in the sources consulted.

The Librarian of Congress, Carla Hayden, called it an extraordinary gift to the Library and to the nation. David Fulton, explaining the gift, said that his wife Amy's own existence reflected the safe haven the United States had given her mother's family after they fled the Holocaust in Austria, and he described the donation as a capstone for the couple's collection. On 14 May 2025 the Library marked the gift with a concert at which Roberto Diaz again played the instrument, this time as its owner rather than its guest, accompanied by the mezzo-soprano Judy Zhuo and the pianist Lynn Ye; photographs from that concert, taken by the Library's staff photographer Shawn Miller and released without copyright restriction, are the basis of the images in this record.

The viola's catalog name changed with its ownership. It is now recorded as the Fulton, ex-Baird, Tuscan-Medici, carrying the names of the family that let it go and the family that brought it home, ahead of the older Medici association it has carried since the seventeenth century.

Joining the collection

The gift brought the Library's Stradivari holdings to six instruments: the Whittall quartet of the 'Betts', 'Ward' and 'Castelbarco' violins and the 'Castelbarco' cello, the Whittall 'Cassavetti' viola of 1727, and now this second viola of 1690. Alongside them the Library holds the 'Kreisler' violin by Giuseppe Guarneri del Gesu, given by Fritz Kreisler in 1952, and the 'Brookings' violin by Nicolo Amati, given in 1938. All are kept in the Whittall Pavilion of the Thomas Jefferson Building and made available, under the collection's long-standing mandate, for research and public performance rather than sealed away as trophies.

Technical evidence

Top wood and dendrochronology
Fine-grained spruce. Dendrochronological analysis dates the outer growth ring of the top wood to 1683, seven years before the instrument was made, and finds a grain pattern consistent with other Stradivari instruments of the 1690s.2
Back, ribs and scroll
Two-piece back and matching ribs and scroll, all of quarter-cut maple.7
Varnish
Oil varnish, described in one source as orange to light brown and in another as yellow-golden; both descriptions are given here rather than resolved to one, since the sources consulted do not agree.76
Arching
High, barrel-shaped arching typical of Stradivari's work in the last decade of the seventeenth century: back arching rises to 19.5 mm, top arching to 18.7 mm.2
Dimensions
Length of back 41.4 cm; upper bouts 18.7 cm; middle bouts 13.1 cm; lower bouts 24.3 cm, sizing it as a contralto (alto-register) viola rather than the larger tenor form of its sibling instrument in Florence.6
Filled holes in the lower ribs
Six holes below the saddle, filled with beech pins, first recorded by the Rudolph Wurlitzer firm when the instrument reached the United States in the 1920s. The Library of Congress reads them as evidence either of a former five-or-more-string setup or of an unusual historic tailpiece attachment; neither explanation is confirmed.25
Fingerboard and varnish shadow
When a later fingerboard was removed, the varnish beneath showed darker where the original fingerboard had sat, a band 78 mm down from the upper edge matching the old fingerboard's width, with a 60 mm strip left unvarnished at the neck end, consistent with Stradivari's practice of varnishing the instrument with the fingerboard already in place.2
Inscription
Inside the top, treble upper bout, in pen: 'The Medici Stradivari / A.H. June 1913', written by Alfred Hill of W. E. Hill and Sons at the point the firm acquired the instrument.25

Provenance

  • 1690 -
    Ferdinando de' Medici, Grand Prince of Tuscanydocumented

    Made in Cremona by Antonio Stradivari as part of a set later called the Medici quintet (two violins, a cello, and eventually two violas), associated with the Cremonese nobleman Bartolomeo Ariberti and the Florentine court of Ferdinando de' Medici. An older cataloging tradition names the recipient as Ferdinando's father, Grand Duke Cosimo III; this record follows the more specific sourcing crediting Ferdinando.45

  • 1690 - 18th century
    Unrecordedunknown

    The Medici quintet was broken up at an unrecorded date. The tenor and contralto violas had gone their separate ways by the late eighteenth century, the tenor remaining in Florence and the contralto (this instrument) leaving Italy. No mechanism or date for the dispersal is given in the sources consulted.12

  • 18th century - 1803
    The Gianfigliazzi family of Florence, then an unnamed Englishman resident in Florencedocumented

    Per W. E. Hill and Sons' 1902 monograph, the viola arrived in England with the last descendant of the noble Gianfigliazzi family of Florence, and was sold in 1803 to an Englishman living there.25

  • 19th century - 19th century
    Bright and Jones, then Alexander Glennie, then F.F. de Rougemont, then Avery Tyrelldocumented

    Reconstructed from the Betts notebook and preserved in the Cozio Archive: Bright and Jones to Alexander Glennie; Glennie's son-in-law F. F. de Rougemont; then to Avery Tyrell, who inherited it from his father Edward. No individual dates are given in the sources consulted.5

  • 1913 - 1913
    W.E. Hill and Sonsdocumented

    Acquired from the Tyrell heirs. Alfred Hill inscribed the top interior 'The Medici Stradivari / A.H. June 1913' and the firm assessed it as one of the finest of the ten existing Stradivari violas.25

  • 1913 - 1924 or 1925
    Richard Bennett, then W.E. Hill and Sons again, then the Rudolph Wurlitzer Companydocumented

    Sold to Richard Bennett in 1913 or 1914, later reacquired by the Hills, then sold through the Rudolph Wurlitzer Company of New York.5

  • 1924 or 1925 - 1957
    Herbert N. Strausdocumented

    The Library of Congress dates the sale to 1925; the Wurlitzer-Hill chain preserved by the Cozio Archive implies 1924. Straus, an amateur musician, was a son of Isidor and Ida Straus, co-owners of R. H. Macy and Company; Isidor Straus died aboard the Titanic in 1912.2513

  • 1957 - 1960
    Cameron Bairddocumented

    Bought from the Straus estate in 1957. W.E. Hill and Sons issued a written certificate of authenticity on 2 February 1957. Baird, a violist, founded and chaired the music department at the State University of New York at Buffalo; during his ownership the viola was loaned for performance to Boris Kroyt and Alexander Schneider of the Budapest String Quartet.45

  • 1960 - 1977
    Jane Baird (Cameron Baird's widow)documented

    Baird died in 1960; the instrument passed to his widow.45

  • 1977 - 2025
    Jane Baird, then the Baird family through the Tuscan Corporationdocumented

    Placed on continuous loan with the Library of Congress in 1977. Ownership remained private throughout; the instrument was displayed publicly, played annually in the Library's Stradivari Memorial Concert, and photographed as part of the Library's 2018 ten-instrument Stradivari display, all while still on loan rather than owned by the Library.89

  • 2025-04-30 - present
    Library of Congressdocumented

    Given outright on 30 April 2025 by David and Amy Fulton (20 million dollars in cash) and the Baird family through the Tuscan Corporation (the remaining value, an in-kind contribution), against a total assessed value of 30 million dollars. The precise structuring and tax treatment of the gift are not stated in the sources consulted. The instrument's catalog name changed to Fulton, ex-Baird, Tuscan-Medici.34511

Open questions

  • How many Stradivari violas actually survive: sources consulted give both 'around ten' and 'around a dozen', and this record has not been able to reconcile the two figures.
  • When and by whom was the original Medici quintet broken up, and when precisely did the tenor and contralto violas go their separate ways? No date is given in the sources consulted.
  • What are the exact dates of the nineteenth-century English ownership chain (Bright and Jones, Alexander Glennie, F. F. de Rougemont, Avery Tyrell)? The sequence is documented but undated in the sources consulted.
  • Did Herbert N. Straus buy the viola in 1924 or 1925? The Library of Congress's own account and the Wurlitzer-Hill chain preserved by the Cozio Archive disagree by a year.
  • What became of the second violin and, if it survived independently, the cello from the original Medici quintet? Only this viola, its sibling tenor viola, and one violin ('Medici, Tuscan') are identified with confidence in the sources consulted.
  • What appraisal methodology set the viola's value at 30 million dollars in 2025, and exactly how were the Fultons' cash gift and the Baird family's in-kind contribution structured and administered? Not stated in the sources consulted.
  • Whether either the Fulton or Baird contribution to the 2025 gift claimed a U.S. charitable tax deduction, and on what appraised basis, is not addressed in the sources consulted.
