August Langenberger was Anaheim's first merchant, establishing a general store in 1858 when the first vineyards were being planted. Langenberger was the son-in-law of Juan Pacifico Ontiveros - the rancher who sold the original Anaheim townsite to German colonists.

The general store - on Lincoln Avenue between Lemon Street and Anaheim Boulevard - also served as a post office, Wells Fargo depot, hotel, restaurant, bar and home for the Langenberger family.

A German native, Langenberger emigrated to the United States in 1846. He joined the California gold rush two years later before heading south to Anaheim in 1850.

Langenberger remarried after his wife died, naming a city street - Clementine - after his new bride, Clementina.

He served on the city council, school board and county board of supervisors.
