The first chief to remain in office for any time was John M. Glass; appointed in 1889, he served for eleven years and was a driving force for increased professionalism in the force. By 1900, there were 70 officers, one for every 1,500 people; in 1903, with the start of the Civil Service, this force was increased to 200, although training was not introduced until 1916. The rapid turnover of chiefs was renewed in the 1900s as the office became increasingly politicized; from 1900 to 1923 there were sixteen different chiefs. The longest-lasting was Charles E. Sebastian, who served from 1911 to 1915 before going on to become mayor.
