Kenneth Frederick Hahn (August 19, 1920 – October 12, 1997) was a member of the Los Angeles County Board of Supervisors for forty years, from 1952 to 1992.

[5] Hahn entered the Navy as an enlisted man in 1942 and earned a commission after studying at naval schools at Northwestern and Notre Dame universities.

[7] Hahn unseated Charles A. Allen, the incumbent in Los Angeles City Council District 8, in 1947.

He was supported by students at Pepperdine College, which at that time was located in the 8th District: they circulated his nominating petitions and did house-to-house campaigning for him.

He urged a delay in the building of a new jail in Lincoln Heights until the council could hear from Assemblyman Vernon Kilpatrick, who declared in a letter that the proposed lockup represented "outmoded thinking concerning jail programs" and suggested that the money be spent for more "sunshine and fresh air" prison camps.

The council adopted Hahn's resolution asking Air Pollution Control Director Gordon P. Larson to appear before it to report on the worsening smog situation in Los Angeles.

Harby also called a suggestion by Hahn for a pay raise for city employees "political prostitution in its lowest form.

Hahn proposed a special police patrol to protect birds nesting on the City Hall grounds.

Win Austin attended a dinner meeting in South Gate to honor the House Committee on Un-American Activities.

[6] In 1970 he joined with his personal physician, cardiologist Walter S. Graf, to establish the first system of emergency paramedic care in California; Hahn is credited with winning support for the then-radical idea from the Board of Supervisors and the state legislature, and persuading then-governor Ronald Reagan to sign the bill authorizing the provision of emergency medical care by trained personnel other than doctors and nurses.

[18] In 1961, Hahn was the only public official to greet Martin Luther King Jr. when he came to Los Angeles "after confronting the police dogs and water hoses of Birmingham".

[21] At the Los Angeles County Transportation Commission, Hahn proposed and eventually achieved consensus in favor of putting a proposition on the ballot that not only included funding for a rail network (controversial in some suburban communities), but also funding for local transit to be spent by the local communities as well as lower bus fares for three years.

[8] A funeral service was held at Faith Dome of Crenshaw Christian Center on Vermont Avenue, and interment followed at Inglewood Park Cemetery.

[27] He is also remembered in the naming of a large park in Baldwin Hills, the Kenneth Hahn State Recreation Area.
