Frank Zeidler
Frank P. Zeidler (born 1912) was a socialist mayor of Milwaukee, Wisconsin from 1948 to 1960.
During his administration, Milwaukee grew industrially and never had to borrow money to repay loans. Federal funding was obtained to complete the highway system that was started under Daniel Hoan. The park system was upgraded.
His brother Carl Zeidler, the so-called "Singing Mayor," also served as mayor of Milwaukee.
Zeidler was instrumental in forming the Socialist Party USA in 1973, and served as its National Chair for many years. He was the party's presidential nominee in 1976, getting on 10 state ballots.
Zeidler is still living and involved in politics as a socialist as he nears one hundred years of age.
