Lynne H. Walling

Lynne Heather Walling (October 9, 1958 – May 28, 2021) was an American mathematician specializing in number theory, who became a reader in pure mathematics at the University of Bristol. She was known for her research in number theory. She died on 28 May 2021.

Walling was born on October 9, 1958, and grew up in northern California. She began her undergraduate studies at the University of California, San Diego, and after a two-year gap continued at Sonoma State University, studying accounting at first but then finishing a bachelor's degree in mathematics. She received her Ph.D. from Dartmouth College in 1987 under Thomas Richard Shemanske.

She then taught at St. Olaf College, Minnesota. She lived in an old farmhouse, which had no indoor plumbing. She built a hand-operated pump, enabling her to install a bathtub in the kitchen, beside a wood-burning stove.

She became a tenure-track Assistant Professor at the University of Colorado, Boulder in 1990. In 1995 she received tenure, and in 2000 became a full Professor. She came to Bristol as a reader in mathematics in 2007. From 2011 to 2015 she was Head of Pure Mathematics, and from 2018 was Director of the Institute of Pure Mathematics.

In 2012, Walling became a fellow of the American Mathematical Society.
