William Henry Heard (born 1935 in Michigan) is a malacologist, and an authority on freshwater mollusks, especially freshwater pelecypods (clams). He is an emeritus professor in the Department of Biological Sciences, at Florida State University.[1]
Heard was the winner of the "Lifetime Achievement Award" for 2001 from the Freshwater Mollusk Conservation Society.[2] He has had two species of mayflies named in his honor: Symbiocloeon heardi Müller-Liebenau[3] and Povilla heardi Hubbard.[4] Heard discovered these insects in Thailand, where they were living within the shells of freshwater clams.
