History of Our City:

Pittsburg has been a city in progress for nearly a century and a half. Located at the point where the Sacramento and San Joaquin rivers meet, Pittsburg is a City of both progress and promise. The earliest recorded history of our town starts in the year 1839 when the Mexican government granted almost 10,000 acres to Jose Antone Mesa and Miguel Jose Garcia. Shortly thereafter the little town was named New York of the Pacific, possibly because the man who laid out the town, Colonel J.D. Stevenson, was a native of New York. This area soon became known as New York Landing and thrived on fishing and canning industries. Following the discovery of coal in the hills three miles south of town, the town was renamed Black Diamond in 1868.

In 1906 Columbia Geneva Steel opened for business, and by popular vote on February 11, 1911, the name was changed to Pittsburg, after the eastern birthplace of the steel industry but without the "H" for simplified spelling.
