Cameron Erskine Thom (June 20, 1825 – February 2, 1915) was a lawyer, a legislator, a Confederate officer in the Civil War, and the 16th mayor of Los Angeles from 1882 to 1884.
After university, he traveled west in a caravan of some 40 young men and arrived in Sacramento in 1849. He gathered gold on the South Fork of the American River, in Amador County, then settled in Sacramento to open a law office. He served in the Confederate Army during the Civil War. He was wounded at the Battle of Gettysburg and ended the war as a captain.[2]
Thom was married twice: first in 1858 to Susan Henrietta Hathwell; and then, after Susan's death in 1862, to her sister, Belle Cameron Hathwell, in 1874. He had four children: Cameron DeHart, Charles Catesby, Belle (Mrs. Arthur Collins of London, England) and Erskine Pembroke.[2][4]
Thom arrived in California in 1849 during the gold rush, and after a few years of successful mining, he studied law in Sacramento. In fall 1853 he moved to San Francisco, where he was a deputy agent for the United States Land Commission; then moved to Los Angeles, where he had a similar job. He was soon appointed Los Angeles County district attorney, and later won the office in an election. He was also elected Los Angeles city attorney for the 1856–58 term.[2][6]
The 1871 land case known as "The Great Partition" divided Rancho San Rafael into 31 sections given to 28 people, including 724 acres (2.93 km2) for Thom. The land belonging to Prudent Beaudry, Alfred Chapman, Andrew Glassell and Thom evolved into Glendale. Thom, Harry J. Crow, B. F. Patterson, B. T. Byram, and Thom's nephew Erskine Mayo Ross were responsible for the creation of the city of Glendale in 1887.[8]
