Watergate historian Stanley Kutler, who successfully fought for the release of
Kutler, who had been in declining health, died in hospice care in the Madison suburb of Fitchburg, according to his son, Andy Kutler.
Andy Kutler said his father "just had a love and a passion for the United States Constitution" and considered the Watergate scandal that drove Nixon from office in 1974 "an affront to the Constitution."
"He wanted to make sure the whole story was heard," Andy Kutler said.
Stanley Kutler taught for 32 years at the University of Wisconsin-Madison, retiring in 1996, and remained a professor emeritus. He was the author of several books, including two on Nixon.
In 1992, Kutler and Public Citizen, an advocacy group, sued the National Archives to force the release of thousands of hours of White House conversations recorded by Nixon's secret taping system. Kutler won the gradual release of 3,700 hours worth of tapes in 1996.
Andy Kutler remembers his father, after winning release of the Nixon tapes, going to the National Archives and listening to the scratchy, "horrible audio recordings."
Stanley Kutler used transcripts of the tapes to write his 1997 book "Abuse of Power." He also wrote "The Wars of Watergate: The Last Crisis of Richard Nixon."
In 2013, he told the Associated Press that the most damning conversation was Nixon telling aides in August 1972 that the Watergate burglars "have to be paid" to keep them silent about the June 1972 break-in at Democratic offices in the Watergate complex.
"That cuts to the whole heart of the matter of obstruction of justice," Kutler said.
Kutler was born Aug. 10, 1934, in Cleveland. He received his bachelor's degree from Bowling Green State University in 1956 and his doctorate from Ohio State University in 1960. He taught history at Penn State University and what is now San Diego State University before arriving at Wisconsin in 1964.
Besides his son Andy, survivors include his wife, Sandra; another son, David; daughter Susan Saltzman; and seven grandchildren. Another son, Jeff, predeceased him.
