# 72nd Wisconsin Legislature

The Seventy-Second Wisconsin Legislature convened from January 12, 1955, to October 21 1955, in regular session.
This was the first legislative session after the redistricting of the Senate and Assembly according to an act of the 1951 session (The implementation of that redistricting act had been delayed to the 1954 election).
Senators representing odd-numbered districts were newly elected for this session and were serving the first two years of a four-year term. Assembly members were elected to a two-year term. Assembly members and odd-numbered senators were elected in the general election of November 2, 1954. Senators representing even-numbered districts were serving the third and fourth year of a four-year term, having been elected in the general election of November 4, 1952.
The governor of Wisconsin during this entire term was Republican Walter J. Kohler Jr., of Sheboygan County, serving his third two-year term, having won re-election in the 1954 Wisconsin gubernatorial election.
