Edward Beaumont, Confederate officer, farmer, and civil engineer, was born on October 21, 1833, in Natchez, Mississippi. He was the son of Jefferson Beaumont (1802–1865) of Kentucky and Sarah Greenleaf (1804–1874) of Mississippi. Beaumont's family moved to Calhoun County, Texas, by 1848, when Jefferson Beaumont became the county judge, a position he held until 1856. Edward Beaumont's parents were both buried in Jackson County, Texas. By 1860 Edward ran a farm near Indianola.
At the outbreak of the Civil War, Beaumont enlisted in Victoria, Texas, as a captain in Company B of Yager's First Mounted Rifles, First Cavalry Regiment on October 11, 1861. Yager's First Mounted Rifles later became Augustus Buchel's Brigade, Slaughter's Second Division, of the First Texas Cavalry. Captain Beaumont was stationed at Fort Brown, Texas, in March of 1863 and Camp Cedar Lake, Texas, in December of the same year. In 1864 he had a combined command of over 100 men and occupied the Louisiana side of the Sabine River. Captain Beaumont was a participant in the battles of the Red River campaign, including Mansfield, Pleasant Hill, and Morgan's Ferry.
Beaumont survived the war and spent the rest of his long life traveling and working in various fields of employment. After the war, Beaumont moved to Mexico where he planted cotton for a year with Judge Terry, a brother of the old colonel of Terry's Texas Rangers. He also worked in the engineering department of the Vera Cruz and City of Mexico Railway. From Mexico, he moved to California, Arizona, and finally New Mexico, where he worked as a farmer, civil engineer, and a miner, respectively. Beaumont never married and died from an accidental gunshot wound on October 20, 1910, in his cabin sixteen miles north of Albuquerque, New Mexico.
