Zoologist Maynard Mayo Metcalf (1868-1940) was the only scientist allowed to testify on the stand at the 1925 Scopes anti-evolution trial. Trained at Oberlin College (B.S. 1889; ScD, 1914) and Johns Hopkins University (1893), Metcalf had been teaching at Oberlin when asked to testify. He had just been appointed research associate and professor of zoology at Johns Hopkins University and, earlier in 1925, as a research collaborator in marine invertebrates (protozoa and mollusca) at the Smithsonian Institutions U.S. National Museum.
