CAMBRIDGE.- Last week one of the great collections of art in the UK celebrated its bicentenary. 200 years to the day of his death, the Fitzwilliam Museum has revealed previously unknown details of the life of its mysterious founder, Richard 7th Viscount Fitzwilliam of Merrion. Research for a new book has shown how his beloved library may have contributed to his death, and how his passion for music led him to the love of his life: a French dancer with whom he had two children, ‘Fitz’ and ‘Billy’.

The Fitzwilliam Museum: a History is written by Lucilla Burn, Assistant Director for Collections at the Fitzwilliam. The book explores the full 200 year story of the Museum and the first chapter focuses on the founder.

She comments: “Lord Fitzwilliam’s life has been described as ‘deeply obscure’. Many men of his class and period, who sought neither fame nor notoriety, nor wrote copious letters or diaries, do not leave a conspicuous record. But by going through the archives and letters that relate to him, for the first time we can paint a fuller picture of his history, including aspects of his life that have previously been unknown, even to staff here at the Fitzwilliam.”

Lord Fitzwilliam died on the 4th of February 1816, and founded the Fitzwilliam Museum through the bequest to the University of Cambridge of his splendid collection of art, books and manuscripts, along with £100,000 to build the Museum. This generous gift began the story of one of the finest museums in Britain, which now houses over half a million artworks and antiquities.

Other than his close connection to Cambridge and his love of art and books, a motivation for Fitzwilliam’s bequest may have been his lack of legitimate heirs. The new details of his mistress help to explain why he never married.

In 1761 Richard Fitzwilliam entered Trinity Hall, Cambridge, and in 1763 his Latin ode, Ad Pacem, was published in a volume of loyal addresses to George III printed by the University of Cambridge. He made a strong impression on his tutor, the fiercely ambitious Samuel Hallifax, who commissioned Joseph Wright of Derby to paint a fine portrait of Fitzwilliam on his graduation with an MA degree in 1764.

Fitzwilliam’s studies continued after Cambridge; he travelled widely on the continent, perfecting his harpsichord technique in Paris with Jacques Duphly, an eminent composer, teacher and performer. A number of Fitzwilliam’s own harpsichord compositions have survived, indicating he was a gifted musician.

But from 1784 he was also drawn to Paris by his passionate attachment to Marie Anne Bernard, a dancer at the Opéra whose stage name was Zacharie. With Zacharie, Fitzwilliam fathered three children, two of whom survived infancy – little boys known to their parents as ‘Fitz’ and ‘Billy’. How the love affair ended is unknown, but its fate was clouded, if not doomed, by the French Revolution.

We do not know what happened to Zacharie after her last surviving letter, written to Lord Fitzwilliam late in December 1790. Her health was poor, so it is possible that she died in France. However, the elder son, ‘Fitz’, Henry Fitzwilliam Bernard, his wife Frances and their daughter Catherine were alive and living in Richmond with Lord Fitzwilliam at the time of the latter’s death in 1816. It is not known what happened to ‘Billy’.

At the age of seventy, early in August 1815, Lord Fitzwilliam fell from a ladder in his library and broke his knee. This accident may have contributed to his death the following spring; and on 18 August that year Fitzwilliam drew up his last will and testament. Over the course of his life he had travelled extensively in Europe; by the time of his death he had amassed around 144 paintings, including masterpieces by Titian, Veronese and Palma Vecchio, 300 carefully ordered albums of Old Master prints, and a magnificent library containing illuminated manuscripts, musical autographs by Europe’s greatest composers and 10,000 fine printed books.

His estates were left to his cousin’s son, George Augustus Herbert, eleventh Earl of Pembroke and eighth Earl of Montgomery. But he also carefully provided for his relatives and dearest friends. The family of Fitzwilliam’s illegitimate son, Henry Fitzwilliam Bernard (‘Fitz’), including his wife and daughter, received annuities for life totalling £2,100 a year.

On his motivation for leaving all his works of art to the University, he wrote: “And I do hereby declare that the bequests so by me made to the said Chancellor Masters and Scholars of the said University are so made to them for the purpose of promoting the Increase of Learning and the other great objects of that Noble Foundation.”

Director of the Fitzwilliam Museum, Tim Knox commented: “The gift Viscount Fitzwilliam left to the nation was one of the most important of his age. This was the period when public museums were just beginning to emerge. Being a connoisseur of art, books and music, our Founder saw the importance of public collections for the benefit of all. But we are also lucky that his life circumstances enabled him to do so - had there been a legitimate heir, he might not have been able to give with such liberality. From the records we have discovered he appears to have been as generous as he was learned: he arranged music concerts to raise funds for charity, and helped many people escaping the bloodiest moments of the French Revolution. We are delighted to commemorate our Founder in our bicentenary year.”

Exhibitions and events for the Fitzwilliam Museum’s Bicentenary will be taking place throughout 2016. These include two key exhibitions opening in February, a retrospective of its history, Celebrating the First 200 Years: The Fitzwilliam Museum 1816 – 2016 , and a major exhibition of Egyptian antiquities, Death on the Nile: Uncovering the afterlife of ancient Egypt
