David Bremner Henderson (March 14, 1840 – February 25, 1906), a ten-term Republican congressman from Dubuque, Iowa, was the speaker of the United States House of Representatives from 1899 to 1903. He was the first congressman from west of the Mississippi River, the last Civil War veteran, the second foreign-born person (after Charles Frederick Crisp), and the only Iowan to serve as Speaker. Early life Henderson was born in Old Deer, Scotland on March 14, 1840. He emigrated to the United States with his parents, who settled in Winnebago County, Illinois in 1846. The family moved to a farm near Clermont, in Fayette County, Iowa in 1849. He attended the common schools, and the Upper Iowa University at Fayette, Iowa. Henderson married Augusta Fox, a fellow student at Upper Iowa University. While pursuing the same course of study they formed a lifelong attachment. After finishing their studies, their paths diverged for a time. Fox returned to her home and Henderson entered the army as a private. He was severely wounded and lost a leg, but he returned to active service and accepted a colonelcy even before fully recovering. After the close of the war Colonel Henderson and Fox were married. Fox was a native of Ohio, but had moved to Iowa at an early age. They had two daughters and one son. The elder daughter married Samuel Peaslee, and the other daughter, Isabelle, was an accomplished musician.

He enlisted in the Union Army on September 15, 1861, as a private in Company C, 12th Iowa Volunteer Infantry Regiment. Henderson was elected and commissioned first lieutenant of that company. In the Battle of Fort Donelson, he was shot in the neck in the final charge over the breastworks. After returning to the Regiment in April 1862, he lost one foot and part of one leg at the Second Battle of Corinth in October 1862. He was discharged on February 26, 1863, due to his wounds, and returned to Iowa. After serving as commissioner of the board of enrollment of the third district of Iowa from May 1863 to June 1864, he re-entered the Army as colonel of the new 46th Iowa Volunteer Infantry Regiment, one of
