Imagine accumulating tens of thousands of fossils? While the exact number of fossils in Bayet’s collection has yet to be determined, estimates range from 20,000 to over 100,000. In 1903, William Holland, Director of the Carnegie Museum, negotiated a blockbuster deal to bring Bayet’s entire collection to Pittsburgh. The deal dazzled the public and made front page news in the New York Times. For over two years, the Section of Invertebrate Paleontology has been uncovering the stories of the collectors and dealers behind Bayet’s magnificent collection. Notable dealers include Lucien Stilwell, Frederick Stearns, and Dr. Friedrich Krantz, to name a few. But what about Bayet himself? What is his story?
Thanks to ongoing translations of the Bayet archive by volunteer Lucien Schoenmakers, we are excited to begin a series introducing Ernest Bayet, the person behind the collection.
How old was Bayet when he sold his fossil collection?
Bayet, who was Born in 1859, was just 44 years old in 1903 when he sold his collection to the Carnegie Museum.
How long did Bayet collect fossils?
Archival documents, that in 1903 arrived in Pittsburgh from Brussels with the purchased materials, indicate Bayet acquired the bulk of his collection in under 20 years. Assuming a range of 20,000 -100,000 fossils, Bayet would have acquired fossils at the blistering pace of 1,000-5,000 specimens per year. When you consider the logistics of shipping, along with the perpetual letter writing required to transact deals in the late 19th century, his acquisition rate is an amazing feat.

Why did Bayet sell his collection?
In July of 1902, Bayet married countess, Maria van der Burch. The Bayet family had their first child in 1903. A second child followed in 1905. Was this a factor in Bayet’s decision to downsize his entire fossil collection? We are not yet sure of Bayet’s plans or motives. For over a century it was rumored that Bayet sold his fossils to pay for a new chateau, or home. In a letter to Andrew Carnegie dated June 8, 1903, William Holland, then Director of the Carnegie Museum, reported this as a possible explanation for the fossil sale. Although we have yet to verify that a chateau was acquired within that period, such a purchase is a possibility.
How long did Bayet live?
The Mysterious Mr. Ernest Bayet died in 1935 at the age of 76. What was his life like after the sale?
