Jo Ann Zimmerman

Zimmerman died of complications of pulmonary fibrosis on October 22, 2019, at the age of 82. She had been suffering from the disease for about 8 years previously.

In 1982, Zimmerman won election to the Iowa House of Representatives where she advocated various health issues, and won the 1986 election for Lieutenant Governor of Iowa, separately from Governor Terry Branstad. As Lt. Governor, Zimmerman advocated for the elimination of her own office (as it was considered a figurehead position) and championed other progressive causes in her position. Zimmerman briefly entered the 1990 gubernatorial election to unseat incumbent governor Branstad, but dropped out to run on the Iowa Democratic Party ticket as Lt. Governor with Donald Avenson (who subsequently lost to Branstad). She left office in 1991.

In 1956, she married Tom Zimmerman, and had five children.
