A.B. "Bert" Curtis was born on a ranch near Salem, Oregon, August 1, 1903. His parents, Charles Garret Curtis of Independence, Missouri, and Elizabeth Ann Milne, who was born near Dundee, Scotland, were early pioneers. When the family moved to Orofino, Idaho, in 1912 Charles Curtis operated the Cottage Hotel for a time before he returned to ranching.

Having attended high school in both Orofino, where he was on the football team, and Plummer, from which he graduated in 1921, Bert entered the University of Idaho where he remained for one year. He then attended Lewiston State Normal School where he received his teacher's diploma after two years of study. He taught and coached athletics in Fernwood for a while, then returned to the University of Idaho for two more years. He married Alene Honeywell of Clear Lake, South Dakota, in Moscow on December 21, 1928. They have five children, four sons and a daughter.

In 1918 he began his 50 year association with the Clearwater Timber Protective Association when, due to the manpower shortage caused by the war, Theodore Fohl hired the 15 year old Curtis as a waterboy, carrying water to the firefighters. He spent his summers until 1925 working for the association, then in May 1926 he began full-time work. In 1927 he was appointed Assistant Chief Fire Warden for the association and a year later was appointed Chief.

In 1966 the Clearwater and Potlatch Timber Protective Associations were combined and Curtis remained Chief Fire Warden of the new organization until he retired in August 1968.

In 1958 he tried unsuccessfully to unseat Gracie Pfost, the Democratic incumbent representing Idaho's First District in the U.S. House of Representatives.

He was a strong supporter of Senator Henry Dworshak on the Bruces Eddy (now Dworshak) Dam issue, and was one of the primary figures in obtaining approval and funds for the construction. In 1972 he was awarded the Department of the Army Certificate for Patriotic Civilian Service for his assistance to the Corps of Engineers in building the dam. Among his other awards are the Idaho Chamber of Commerce Distinguished Citizen award (1968), and a 38 years of distinguished service award presented by public and private Idaho forestry associations in 1956.
