Johannes Seigfried Anderson[1] (July 20, 1887 – April 15, 1950) was a Finnish-born U.S. Army soldier during World War I, and a Medal of Honor recipient.

Little is known of Anderson's early life, other than that he was born in Finland July 20, 1887, and entered the US Army in Chicago, Illinois June 19, 1916.

He made his advance under heavy fire, over open ground, reaching the emplacement and killing the machine gun crew.

Anderson, without aid, voluntarily left the company and worked his way to the rear of the nest that was offering the most stubborn resistance.

His advance was made through an open area and under constant hostile fire, but the mission was successfully accomplished, and he not only silenced the gun and captured it, but also brought back with him 23 prisoners.
