Roger Fisher, a Harvard law professor who developed the Emmy-and Peabody Award–winning public TV program The Advocates, died Aug. 25 in Hanover, N.H. He was 90. His son Elliott told the New York Times that the cause of death was complications from dementia. Fisher proposed The Advocates in 1969, as a co-production of WGBH in Boston and KCET in Los Angeles. The show was one of the first projects at WGBH for Peter McGhee, who went on to become an influential head of national productions at the station.
