Harry Richard Landis (12 December 1899 – 4 February 2008)[1] was, at age 108, the older of the last two American First World War veterans.

John Babcock, a naturalized American, served in the Canadian Army during the war, and also survived Landis.

His experience of mopping the floor at an army hospital included exposure to the Spanish flu, which was actually the leading cause of death worldwide in the year 1918, killing about 75 million people.

Attempting to try to enlist in World War II after the Attack on Pearl Harbor in 1941, he was rejected as "too old".
