Bernard Brock, professor emeritus of Communication at Wayne State University, will be remembered at a memorial service held by Wayne State on April 23 at St. Andrew's Hall, 431 E. Congress in Detroit. Mr. Brock, an expert in political rhetoric and communication and formerly co-director of WSU's Center for Art and Public Policy, died March 31 from complications of a heart valve infection. He was 77. \"In his field he was a national figure,\" said journalist Jack Lessenberry, a Wayne State University journalism lecturer and colleague of Mr. Brock. \"You didn\'t know that because he was very self-effacing and kind man.\" Memorials may be made to Wayne State University's Center for the Arts and Public Policy.
