Some time before 1863 he appeared in San Francisco, either claiming to be George Washington from the outset, or by other accounts, setting up his phrenology business and entertaining fashionable society with readings of their skulls.
According to this second story, he was generally known as "Professor" Freddy Coombs and resembled George Washington so much that after many comments, he became convinced that he was the former President of The United States and took to dressing in uniform.
He wore a Continental Army uniform of tanned buckskin, and set up his headquarters at the saloon of Martin and Horton, where he would study maps while planning his campaigns for the Revolutionary War.
Initially he, Norton, and the two well-known stray dogs Bummer and Lazarus drew equal interest from the San Francisco newspapers who delighted in recounting their exploits.
This caused great amusement and a few days later the Alta California published a story mocking both the men in which they reported that the "light of insanity" could be seen in Coombs's eyes.
In 1868, Coombs was discovered by Mark Twain in New York City, still believing himself to be Washington and still convinced of the effect of his charms on the ladies, whom he entertained by displaying his legs on street corners.
