Charles H. Ackerson (1836–91) came to San Francisco from New York in 1850, at the age of fourteen. Ackerson volunteered with the Howard, Tiger, and California engine companies before he was appointed second Assistant Chief Engineer in 1866 after the professionalization of the department. In 1870, he became the department’s Second Chief Engineer and served until 1871, when David Scannell replaced him.
