The Boulder Hook and Ladder Company No. 1 was the first volunteer fire company organized in Boulder, 16 February 1875. The name was changed to Phoenix Hook and Ladder Company later that same year. Boulder Hose Company No. 1 was organized 13 July 1875, and A. J. Macky Hose Company No. 2 on 5 January 1877. Until 1898, hose carts and hook and ladder wagons were man-hauled. In that year the first horse team was bought by the city, and Robert May became the first paid fire chief.
