Dr. Frank Adrian Pearl was one of 104 Black doctors to volunteer as US Army medical officers during the First World War. Dr. Pearl, whose brother was also a physician, was born in 1886 in Atchison, Kansas and grew up in Butte, Montana. He studied at the Topeka Vocational Institute and Butte Business College, and graduated with honors from Howard Medical School in 1912. Commissioned as a First Lieutenant in 1917, Dr. Pearl served with the 368th Ambulance Company of the 92nd Infantry Division. The US Army was racially segregated at the time, and the 92nd Division, nicknamed the "Buffalo Soldiers Division," was composed of Black combat troops lead mostly by white officers. Two hundred thousand African-American soldiers served in France and about 40,000 of these men, including Dr. Pearl, saw active combat.
In 1918 the Buffalo Division saw action in eastern France in the trenches of the St. Dié sector of the Vosges Mountains. A German counterattack was successfully repelled at Frapelle. The division suffered over 300 casualties later that year during Meuse–Argonne offensive, which was the deadliest campaign in the history of the US Army. Dr. Pearl’s ambulance company evacuated and treated wounded and sick soldiers to army hospitals. He also innovated new methods in handling injured soldiers that helped surgeons avoid amputations and was promoted to Captain. Discharged after the war, Dr. Pearl moved to Los Angeles and opened a medical office. Not only was Dr. Pearl a member of the American Medical Association, the Veterans of Foreign Wars, the American Legion and the California National Guard, but in 1942 he also served on a special committee to celebrate the launch of the SS Booker T. Washington, which was the first liberty ship to be named for an African American. He also served as the head of the Office of National Defense’s National Disaster Relief Committee in Los Angeles. Dr. Pearl's newspaper obituary states that he died at the age of 62 in 1948.
