Named after the Jakob-Kaiser-Platz, which honours the politician Jakob Kaiser.
Jakob Kaiser (1888–1961), a Centre Party and later CDU politician and trade unionist, was in the resistance against the Nazis and went into hiding in 1944; from 1949 to 1957 he was federal minister for all-German affairs. The square, formerly Siemensplatz, was named after him on 12 May 1961, five days after his death. Nearby streets honour resistance fighters.
