From Wikipedia, the free encyclopedia

Clara Brink Shoemaker (20 June 1921 in Rolde - 30 September 2009) was a Dutch-born American crystallographer and a senior research professor at Oregon State University.[1][2][3][4] As a postdoctoral researcher, she worked on the structure determination of vitamin B12 in the group of Dorothy Hodgkin.[1][5] Together with her husband, David Shoemaker, she contributed to the research on transition metal phases and intermetallic compounds.[1][6] They were the first to recognize that interstices in tetrahedrally close-packed metal crystals are exclusively tetrahedral and only have four types of coordination polyhedra.[1][7]

Life[edit]

In 1941, Shoemaker completed her undergraduate degree at the University of Leiden which was closed shortly after due to the Nazi occupation.[2] She then started her graduate studies at the University of Utrecht where she studied under Anton Eduard van Arkel.[2] At the end of the World War II, she completed her doctoral examination.[2] Afterwards, Shoemaker assumed an assistantship at the University of Utrecht and she learned the techniques of X-ray crystallography under the renowned crystallographer Caroline MacGillavry.[2] In 1950, Shoemaker received her PhD from the University of Utrecht and was hired by Anton Eduard van Arkel as an X-ray crystallographer at the University of Leiden.[2] During this time, her research focused on crystal structures of monovalent ions.[2] Starting later in 1950, she worked on the crystal structure of vitamin B12 in Dorothy Hodgkin's laboratory in Oxford for one year.[2] This resulted in three publications co-authored with Hodgkin.[2] The stay was funded by an International Federation of University Women fellowship.[2] In 1953, Shoemaker took a one-year leave of absence and travelled to Massachusetts Institute of Technology to work with David Shoemaker on the structure of transition metals.[2] David Shoemaker renewed her leave of absence contract for another year in 1954. In 1955, Clara Brink Shoemaker and David Shoemaker married.[2] After the wedding, Clara Shoemaker moved to Barbara Low's laboratory at Harvard Medical School.[2] In 1956, her son Robert was born. While taking care of her son, Shoemaker worked from home on the International Tables of Crystallography. In 1959, Shoemaker became a naturalized citizen of the United States of America. Clara and David Shoemaker relocated to Oregon State University in 1970, where David Shoemaker was hired as a chairman and professor of chemistry.[2] Due to the nepotism guidelines of the university, Clara Shoemaker worked as a research associate under Kenneth Hedberg whereas Hedberg's wife Lise Hedberg worked under David Shoemaker.[1] In 1982, Clara Shoemaker was promoted to senior research professor. In 1984, both Clara and David Shoemaker retired from Oregon State University but continued their scientific work.[2]

Research[edit]

Together with her husband, David Shoemaker she contributed to the research on transition metal phases and intermetallic compounds.[1][6] They were the first to recognize that interstices in tetrahedrally close-packed metal crystals are exclusively tetrahedral and only have four types of coordination polyhedra.[1][7]

Selected publications[edit]

Together with Dorothy Hodgkin, she published 3 publications on the crystal structure of vitamin B12:
