Max Weber was a military officer in the armies of Germany and later the United States, most known for serving as a brigadier general in the Union army during the American Civil War.
Born in Achern, in the German state of Baden, Weber graduated from the military school at Karlsruhe in 1843, and served as an infantry lieutenant in the Grand Duke's army.
In 1849, during the Revolutions of 1848, he served with the revolutionaries under Franz Sigel. He emigrated to America, one of a large group of political refugees who came to be as known as the Forty-Eighters. He settled in New York City and worked as proprietor of the Konstanz Hotel in New York.
Weber enlisted to fight in the Civil War as a colonel on 16 May 1861. He raised a German-American unit known as the "Turner Rifles," a company that eventually became a part of the 20th New York Infantry. Weber was stationed at Fort Monroe in Virginia.
He took part in the capture of Fort Hatteras. From September 1861 until May 1862, he commanded Camp Hamilton, near Fort Monroe, being commissioned brigadier general of volunteers on 28 April 1862. He was at Newport News during the fight between the “Monitor” and “Merrimac” in anticipation of a Confederate attack by land.
He took part in the capture of Norfolk, Virginia in May, and then commanded at Suffolk until September, when he was ordered to the Army of the Potomac where he commanded the Third Brigade, Third Division, Second Army Corps in the Army of the Potomac. Weber's brigade was the first to attack the Sunken Road during the Battle of Antietam. His right arm was grievously wounded in the ill-fated attack on the Confederate positions.
The injury forced Weber off to a series of desk assignments for the duration of the conflict. He served on administrative duty in Washington, D.C., in 1863. He served under Gen. David Hunter and Gen.
Franz Sigel in the Shenandoah Valley in 1864. He was the garrison commander of Harpers Ferry and repelled Jubal A. Early's July 4–7 raid. Weber resigned his commission on 13 May 1865.
After the war, he was assessor of internal revenue in New York in 1870-72, and then collector until April 1883, when he resigned. Weber served as U.S. counsel in Nantes, France.
