Andrew Huxley, a British physiologist who shared the 1963 Nobel Prize with two other scientists for research on how nerve impulses are transmitted, died May 30 at age 94.

Mr. Huxley, who was the half-brother of writer Aldous Huxley, author of "Brave New World, and a member of a distinguished British scientific and literary family, was drawn to science at an early age. He experimented with microscopes as a boy and, when he was 12, received a lathe that he used to build scientific instruments throughout his career.

He was in his early 20s when he began his research on the electrical and chemical processes that control the actions of muscles.

He teamed with Alan Hodgkin, a fellow scholar at Trinity College, and began conducting experiments on nerve tissue from a giant squid.

He was knighted in 1974.
