IN MEMORIAM: DAVID B. PEAKALL, 1931–2001

and in 1933, Marguerite Heydweiller (later Mrs. Fred Baumgartner). Twomey's studies of the Bonaparte's Gull (Larus philadelphia) in northern Alberta and at Churchill were published in The Auk (1934). A popular account of his Churchill observations appeared in The Beaver (1937), and ecological studies with V. E. Shelford were published in Ecology. The collecting experience gained at Churchill led to lifetime employment at the Carnegie Museum in Pittsburgh for both Lloyd and Twomey. At the Carnegie Museum, Twomey was an assistant and field collector in ornithology, July 1936 through 1944; associate curator, 1945; curator of ornithology, 1946-47, and then director of education, 1948 through retirement in December 1973. He studied the birds of the Uinta Basin, Utah, in 1937. His first major expedition to western Ungava, beginning in January 1938 and lasting into early September, with spring and summer spent on the Belcher Islands, was chronicled in his book, Needle to the North (1942). He collected in Chile (Tierra del Fuego), Peru and the Galapagos Islands in 1939. He took part in Mellon-financed big game hunting expeditions to Africa in 1960, 1961, 1963, and 1964. In 1948, he inaugurated the Carnegie Institute Society lecture series. Both before and after retirement he showed wildlife and travel movies of exotic places such as Africa, Afghanistan, Mongolia, and Russia. On his son's death, these movies and slides were donated to Carnegie.
