Elcan Heydenfeldt

Elcan Heydenfeldt was an American politician who served in the California State Assembly and California State Senate.
Heydenfeldt was elected to the state senate in 1850, representing San Francisco, and was elected its second president pro tempore. He was then elected to the state assembly's 6th district in 1852, being the first person to go from serving in the state senate to the state assembly.
In 1853, Heydenfeldt and four other assemblymembers all resigned their seats. All but one, including Heydenfeldt, then all ran in the special elections for the vacant seats, and were reelected.
California Supreme Court justice Solomon Heydenfeldt was his brother.
