Matthew Shear, 57, a gregarious and widely loved publisher, died Wednesday at his home in Manhattan after a three-year battle with lung cancer, according to St. Martin's Press, an imprint of Macmillan.

Mr. Shear had worked with authors including Doris Kearns Goodwin, Shirley MacLaine, Janet Evanovich, and Augusten Burroughs. He joined St. Martin's Press in 1995 and headed it since 2010. In a companywide e-mail, Macmillan chief executive John Sargent cited Mr. Shear's "outgoing personality," outsized laugh, and his passion for making books succeed.

A native of New York City who attended Hofstra University, Mr. Shear broke into publishing in 1977 as publicity manager for the New American Library. He spent a decade at Bantam Books and also worked at Ballantine Books and at Berkley Books. - AP
