WASHINGTON — Former U.S. Rep. Pat Schroeder, a pioneer for women’s and family rights in Congress, died Monday night. She was 82. Schroeder’s former press secretary, Andrea Camp, said Schroeder suffered a stroke recently and died at a hospital in Florida, the state where she had been residing. Schroeder took on the powerful elite with her rapier wit and antics for 24 years, shaking up stodgy government institutions by forcing them to acknowledge that women had a role in government. Her unorthodox methods cost her important committee posts, but Schroeder said she wasn’t willing to join what she called “the good old boys’ club″ just to score political points.
