Elizabeth Lack

With the end of the war, she applied for employment at the Edward Gray Institute of Field Ornithology at the University of Oxford. When her resume reached Richard Fitter, he passed it on the institute's new director, the prominent ornithologist David Lack, who was seeking a secretary. When Lack received Elizabeth's resume, Fitter had attached a note: "Here's another for your reject file", but Lack interviewed and hired Elizabeth Silva for the position, effective January 1, 1946, and then, noting her passion for birds, invited her to become a part-time field assistant, helping him perform observations in Wytham Woods, located northwest of Oxford.[1]

Elizabeth started off monitoring nests of European robins and tits in Wytham Wood as well as European swifts breeding in the tower of the Oxford University Museum.[3] According to the museum, the tower's colony of swifts has been part of research studies since May 1948 and is "one of the longest continuous studies of a single bird species in the world, and has contributed much to our knowledge of the swift."[3]

In 1948, Elizabeth and David announced their engagement and married on July 9, 1949, taking their honeymoon trip to the Norfolk coast. They had four children: Peter Lack (born 1952, a biologist), Andrew Lack (born 1953, also a biologist and academic), Paul Lack (born 1957, a freelance teacher), and Catherine Lack (born 1959, a university chaplain).[1]

After her marriage and changing her name to Elizabeth Lack, she continued her research, travelling to the French Pyrenees with her husband at least twice to study the birds and insects that migrated southward toward Spain, through high mountain passes. Elizabeth published several papers about their observations, which have been called "pioneering discoveries".[1]

David Lack died of cancer at age 62 in March 1973 with his final book unfinished. Elizabeth and son Peter Lack (aided by James Monk) completed the book and supervised its printing, Island Biology, Illustrated by the Landbirds of Jamaica (University of California Press, 1976).[1]

Elizabeth Lack is widely credited for her "prodigious amount of work" to produce the "massive and authoritative" A Dictionary of Birds compiled for the British Ornithologists' Union with co-editor Bruce Campbell,[4] for which she was awarded an honorary life membership in that organization.[1] In the preface of the tome of more than 800,000 words, Frances James, then president of the American Ornithologists' Union claims it is important for all bird lovers. "For students, it will serve as an entrance to the present status of the field. For scientists it will serve as a research tool and a bridge between disciplines."[5]

In Oxford, the Lacks lived in a flat in Park Town, and later on Boars Hill, just south of the city. Elizabeth Lack died there on 31 July 2015 at age 99.[1]
