What did john sutter do before he came famous?

Before he became famous for his association with the California Gold Rush, John Sutter was a Swiss immigrant who established Sutter's Fort in Sacramento, California, as a trading post and agricultural settlement. He initially sought to create a prosperous farming community, focusing on cattle ranching and agriculture. His efforts to build a successful enterprise laid the groundwork for his later prominence when gold was discovered at his mill in 1848, leading to the massive influx of fortune seekers to California.
