Frank 'Ket' Kettlewell (December 5, 1889 - June 11, 1969) was an American photographer, mapmaker, painter, and cartoonist. The son of Libbie and B. F. Kettlewell, he was born in St. Helena, California, and attended St. Helena High School. Kettlewell arrived in San Francisco after the 1906 earthquake and fire with a shipment of relief supplies and ended up staying in San Francisco and living with his grandfather. Kettlewell attended the Hopkins Art School beginning in 1907. In 1912 he started working for the Oakland Tribune, where he would work in various capacities, including as Art Director, until at least 1966. It is unclear exactly when Kettlewell became the Art Director, but estimates place this promotion to around 1949 until his retirement. 'Ket' became a recognizable part of the Tribune, known for the 'Ket's Eye View' photographs that were printed in the paper, as well as his political cartoons. He signed all of these cartoons with the signature 'KET' and a small black bird, who sometimes played a role in the cartoon or commented on it in some way. Kettlewell also contributed artwork to a long running column entitled 'Your Town', on which he worked with Jack Burroughs. Kettlewell also drew maps that accompanied features about trips around the region that appeared in the Tribune. Kettlewell served as the President of the Oakland Press Club from 1925 - 1926 and as a judge for several different photography contests sponsored by the Tribune. It is believed that he is one of the founding members of the East Bay Astronomical Society and he served as one of its directors for at least twenty-five years. In 1948, Kettlewell designed a postage stamp for the United States Postal Service commemorating the 100th anniversary of the discovery of gold in California and in 1952 he received and award for work in traffic safety from the Eastbay Chapter of the National Safety Council for a series of photomontages that appeared in the Oakland Tribune in connection with traffic safety. Kettlewell married Beatrice Jackson in 1913, who suffered a horrific broken leg and internal injuries in 1922 when a very large tree fell on their car outside Modesto, California. This accident was caused when a road gang failed to properly fall a tree and the tree ended up on top of the Kettlewell's car. In addition to Mrs. Kettlewell's injuries, a young woman who was accompanying them, a Miss Grova Loeber, was killed in the accident. Kettlewell was driving and both women were seated in the back seat. Kettlewell was a very active man and an inveterate tinkerer that would design and build his own tools. One such project involved creating a gem polisher for a friend. His other hobbies included metalworking, woodworking, and stamp collecting.
