Addison Emery Verrill (February 9, 1839 – December 10, 1926) was an American invertebrate zoologist, museum curator and university professor.
As a boy he showed an early interest in natural history, building collections of rocks and minerals, plants, shells, insects and other animals.
[4] Two years after graduation from Harvard, he accepted a position as Yale University's Sheffield Scientific School first Professor of Zoology,[5]: 8 and taught there from 1864 until his retirement in 1907.
The process of overhauling the collection required identifying various species, selecting type specimens and making up a set of duplicates to be sent back north to Harvard.
His Report upon the Invertebrate Animals of Vineyard Sound (1874), with Sidney Irving Smith, whose sister he married, is a standard manual of the marine zoology of southern New England.
