IN MEMORIAM: ERNST MAYR, 1904–2005

Abstract

Ernst Walter Mayr was born on 5 July 1904 in Kempten in southern Bavaria, Germany, and passed away quietly and peacefully on 3 February 2005 in Bedford, Massachusetts. His two daughters were at his bedside during his last hours. At the time of his death, he was the oldest member of the AOU and one of its longest acting, having joined in 1929. He was elected a fellow in 1937 and served as president from 1957 to 1959. Inspired by his parents' interest in natural history, he became a naturalist at an early age and remained one throughout his life. By the time he was a teenager, Ernst could identify all of the local birds by sight as well as by call. Just after graduating from the Gymnasium in Dresden in 1923, he observed a pair of Redcrested Pochards, the first that had been seen in central Germany since 1846. Armed with a letter of introduction, Ernst interrupted his trip to the University of Greifswald and medical studies to visit Erwin Stresemann at the Natural History Museum in Berlin. Stresemann was convinced of Ernst's sighting of the ducks and, impressed with his enthusiasm for ornithology, invited Ernst to work in the museum during vacations. Soon Ernst became enmeshed in systematic ornithology. As he said many years later, this was as if he had entered paradise. Stresemann convinced Mayr to change from medical studies to zoology and ornithology, with a promise of an expedition to a tropical land once he completed his Ph.D. Before starting his studies with Stresemann, Mayr completed his basic medical courses at Greifswald, becoming a Candidate in Medicine, which would allow him to complete his medical training if his plans to become a zoologist did not work out a concern that proved unwarranted. Ernst Mayr started his training in Berlin in March 1925 and completed his Ph.D. in June 1926, just before his 22nd birthday. He began an assistantship at the Berlin Museum on 1 July 1926. Several attempts at the promised tropical expedition failed until a combined expedition to New Guinea for Lord Rothschild at the Tring Museum and for the Berlin Museum (with additional support from the American Museum of Natural History [AMNH] and Dr. L. Sanford) was organized. The work in New Guinea was successful and before Ernst could return to Europe in 1929, he was invited to take part in the AMNH's Whitney South Sea Expedition to the Solomon Islands. Ernst finally returned to Germany in April 1930, having been away for over two years. Mayr's work in the Solomon Islands greatly impressed Dr. Leonard C. Sanford, a patron of the AMNH Department of Ornithology, who urged Mayr's appointment to the department to work on the collections amassed by the Whitney South Sea Expedition. Mayr arrived in New York on 19 January 1931 for a one-year temporary appointment. With the acquisition of the Rothschild collection, Mayr was offered a permanent position at the AMNH. He stayed at the AMNH for the next two decades as the Whitney-Rothschild Curator, working on perhaps the best collection of birds that had ever existed for the analysis of geographic variation, speciation, and island biogeography. During his time at the AMNH, Mayr published his List of New Guinea Birds (1941), which is still the basic reference on this avifauna, and Systematics and the Origin of Species (1942), which
