Paul was born in Germany and worked as an apprentice blacksmith and wagon maker until immigrating to the United States in 1889.
[2][4] San Francisco ordered two custom searchlight trucks for the fire department in 1928 at a cost of $18,000 a piece.
The city also purchased a 1926 Kleiber Tractor to tow a 75-foot water tower (WT-3) designed by Henry H. Gorter for fire fighting.
[2] Keibler's trucks sold well, but the refusal to use assembly line techniques led to the cars being rather expensive.
Kleiber acquired the Studebaker franchise for San Francisco and continued to produce trucks but finally ceased operations in 1937.
