Erratum

In the Spring 2012 article by Stanley Blumenthal,“Earl Sutherland and the Discovery of Cyclic AMP” (volume 55, number 2, pages 236–49), Sutherland’s death date is listed incorrectly as 1975 in the title and abstract.The correct date, 1974, is given in the first paragraph of the text. Perspectives in Biology and Medicine regrets this error.
