Eschmeyer’s Catalog of Fishes is the definitive global source, with the Latin name for 65,000 species compiled by biologists at the California Academy of Sciences under the leadership of Bill Eschmeyer of San Anselmo, who spent 40 years on an odyssey that took him to every museum with a collection of dead fish in jars. The database he created, which started before the Internet, was still growing and being refined long after Eschmeyer retired and moved to the East Coast to be near his three adult children. He died Dec. 30 at an assisted care facility in Nashua, N.H., said his daughter Lanea Tripp, who was named for an 18th century Swedish biologist her father admired. Eschmeyer had suffered from dementia compounded by long COVID. He was 85.
