James Henry Blake

James Henry Blake (July 8, 1845 – July 20, 1941) was an American zoologist and scientific illustrator who worked for the Museum of Comparative Zoology at Harvard University. He later served as an artist for the United States Fish Commission and the U.S. Geological Survey. The scientific literature contains many of his illustrations.

Life and career Blake was born in Boston on July 18, 1845. He received his schooling in Provincetown, Massachusetts, and in 1864 he enrolled in the Lawrence Scientific School at Harvard University. At Harvard, he worked as a student assistant in the conchology department of the Museum of Comparative Zoology, organizing the specimen collections under the tutelage of Louis Agassiz. In 1868, he sketched and recorded the features of mollusks collected during the 1865–66 Thayer Expedition to Brazil. In 1871, Blake accompanied the Hassler Expedition as Agassiz's assistant on this two-year deep-sea dredging trip, during which he drew specimens and supervised the fishing operations that gathered up 30,000 fish specimens. Blake's 152-page scrapbook, filled with clippings and notations chronicling the expedition, is "one of the Ernst Mayr Library’s most prized holdings." and Joel Asaph Allen. He co-founded the Boston Malacological Club, serving as the club's president from 1918 to 1919. He was a member of the Boston Society of Natural History from 1870 until his death and served on its governing council. In 1894–95, he was president of the Cambridge Art Circle. Besides his scientific work, he studied art in New York, painted landscapes, and moonlighted as an art teacher.

Blake married Lucinda Smith Critchett (1844–1907) in Provincetown in 1871 and had two sons with her. He died on July 20, 1941, at the age of 96 in Somerville, Massachusetts. He was buried in Mount Auburn Cemetery. Perhaps the last surviving student or employee of Louis Agassiz at the time of his death, he bequeathed most of his personal collections and artwork to the Museum of Comparative Zoology. A collection of his colored drawings of whales and mollusks made its way into the collection of the Boston Museum of Science.
