# Jonathan Brostoff

Jonathan Brostoff (September 25, 1983 – November 4, 2024) was an American Democratic politician from Milwaukee, Wisconsin. He was a member of the Wisconsin State Assembly, representing Wisconsin's 19th Assembly district from 2015 through 2022. He subsequently served on the Milwaukee Common Council from 2022 until his death in November 2024.

## Early life

Jonathan Brostoff was born and raised in Milwaukee, Wisconsin. He began working and volunteering for area non-profit organizations from the age of 14; he was a youth facilitator for "The Other America Tour," a social justice public education program for high school students in Wisconsin that was organized by the ACLU of Wisconsin and worked for several years with Pathfinders Milwaukee, a non-profit that provides shelter and support for homeless or at-risk teens.
After graduating from Milwaukee High School of the Arts, Brostoff joined AmeriCorps and was matched with Milwaukee's Family Support Center, a homeless shelter. In his role at the shelter, Brostoff worked to get free legal assistance for shelter residents, ran a day-care center, recruited volunteers, and coordinated other entertainment and enrichment programming. During that time, he also began volunteering with Tikkun Ha-Ir ("Repairing the City"), an organization that engages Milwaukee's Jewish community in civic activities. He became a member of that group's board in 2008.
After his term with AmeriCorps ended, he resumed his education at the University of Wisconsin–Milwaukee. While in college, he interned for U.S. Senator Tom Harkin (D–Iowa) in Washington, D.C. He was also chairman of the UWM College Democrats and co-president of UWM's Campus Organization for Israel. He graduated with his bachelor's degree in political science in 2011.

## Political career

After graduating from college, Brostoff worked as a legislative aide to Milwaukee County Supervisor Jason Haas, then served as district director for state senator Chris Larson (D–Milwaukee).
In the Fall of 2013, Brostoff's state representative, Jon Richards, announced he would forgo re-election to seek the Democratic nomination for Attorney General of Wisconsin. Brostoff decided to run for the open seat in the 19th Assembly district. The district comprised all of Milwaukee's lakeshore neighborhoods, including Bay View, the Historic Third Ward, the University of Wisconsin–Milwaukee campus, and Brostoff's home upper east side.
The overwhelmingly Democratic district drew several strong candidates, including Milwaukee County board chair Marina Dimitrijevic, prominent defense attorney Daniel Adams, and labor lawyer Sara Geenen. Adams and Dimitrijevic had prior history as political rivals, and their primary also served as a proxy fight between rival power centers in Milwaukee politics. Dimitrijevic was endorsed by Milwaukee's mayor, Tom Barrett, and Milwaukee's U.S. representative, Gwen Moore. Adams had the endorsement of Milwaukee County executive Chris Abele. From this active primary field, Brostoff prevailed with 35% of the vote. Brostoff's only opponent in the general election was independent United States Pirate Party candidate, Joseph Thomas Klein; Brostoff won with 81% of the vote.
Brostoff was re-elected without opposition in 2016 and 2018, and easily won a fourth term in 2020.
In 2022, Brostoff announced his intention to run for a seat on the Milwaukee Common Council rather than running for another term in the Assembly. Brostoff made the announcement after sitting 3rd district city councilmember Nik Kovac stepped down to assume the role of Budget and Management Director for the City of Milwaukee. Brostoff won the special election on November 8, 2022, and was sworn in a week later.

Brostoff was an avid Magic: The Gathering player, consistently placing first on Magic: The Gathering Online during cube leagues. He helped to found and manage CubeCon, an annual convention dedicated to Magic: The Gathering cube.
On November 4, 2024, Brostoff was found dead in Milwaukee County's Greenfield Park. The Milwaukee County Medical Examiner's Office later reported Brostoff's cause of death was by suicide. He was 41.
