Hello Amador County Historians:

Attached is my first attempt to contribute to the library of Amador County history. This report covers the history of one of our lesser known mines, the Hardenberg, located in the Middle Bar region south of Jackson.

I first want to thank the many who helped me during my research - from the museum, county records and archives. You were all very helpful, and patient, with the voluminous requests for information I used to compile this draft report.

Next, I would be happy to incorporate changes into a new revision. Regardless, I hope you find this to be an interest addition to our collective history. Thanks for reading.

James Richmond (J. R.) Hardenbergh

The namesake of our mine is James Richmond (or more commonly, “J. R.”) Hardenbergh. He immigrated to California in 1849 from New Jersey, and settled in Sacramento. There, he quickly established himself in business and politics. He served as one of its earliest mayors, first in 1850, and then again in 1852. He was appointed by President James Buchanan as Postmaster of Sacramento, and later by President Ulysses S. Grant as U.S. Surveyor General for California.

THE subject of this sketch was born in the city of New Brunswick, in the State of New Jersey, on the 14th day of January, A. D. 1814. His parental great grand-father was the Rev. Jacob R. Hardenbergh, an eminent divine of the Reform Dutch Church of America, and the first president and founder of Queen's (now Rutgers) Col-lege, in New Jersey. His grandfather, Jacob R. Hardenbergh, was a member of the New Jersey bar. His father, the late Cornelius L. Hardenbergh, who died in 1861, was an advocate and counsellor of distinguished ability. We take the genealogy of the Hardenbergh family from all address delivered by Justice Bradly, of the U. S. Supreme Court, at the centennial celebration of Rutgers College in the year 1872. Young Hardenbergh was very delicate and frail, and was in poor health on his arriving at manhood, and was feeble until the invigorating climate of California restored . . .
