About James Denver Glennan

Lived 1862 – 1927 (aged 65). James Denver Glennan was an American military personnel.

Brigadier General James Denver Glennan (March 2, 1862 – December 24, 1927) was a senior United States Army officer in the Medical Corps. Beginning his career in 1888 on the frontier during the Indian Wars, Glennan served in the military until his death in 1927. By then he held command of various hospitals and posts in Cuba, the Philippines, France, and the continental United States. Immigrating to the United States as a child in 1828 from County Meath, Ireland, Patrick's family eventually settled in Rochester. Graduating in medicine from Geneva College in 1850, he returned to his home of Rochester where he married his wife, raised a family, and practiced medicine until the outbreak of the Civil War.

Patrick was first appointed acting assistant surgeon with the Union Army in 1862 and served in this capacity until becoming commissioned as assistant surgeon, United States Volunteers, in May 1864. Mustering out in November 1867, he was the last surgeon of volunteers to have done so.

His next assignment was at Fort Sill, Oklahoma. Arriving there in 1892, he would remain at the post for the next five years at the same time that Geronimo and other Apache prisoners were housed there. Scott was commander of Troop L, 7th Cavalry, which was an Indian scout unit. Both men established a strong relationship with the Native Americans on the post. At one point an outbreak of measles occurred among the native children. Glennan "labored with them incessantly," with the help of Scott and three other soldiers. The camp was quarantined and losses were small. Grateful, the soldiers of Troop L pooled their money together and presented Glennan with a piece of silver.

Glennan became greatly concerned with the welfare of Apache children at Indian boarding schools. In a letter that he composed on November 1, 1895, he described the bad practices of Carlisle Indian Industrial School in detail. He recalled an experience that he had with one child:

Glennan believed that returning infected children to the healthy dry atmosphere of the American Southwest as early as possible would give the sufferers "a chance for life." This would also prevent outbreaks in the tribes as sufferers became infectious in the later parts of their disease.

During a time that organized Native American companies within the army faced staunch criticism by officers, Glennan wrote an article supporting their existence in an 1895 issue of the Journal of the Military Service Institution of the United States. He acknowledged that not all companies had been successful in nature, with a number of them experiencing a variety of failures, yet "it is time for those who have seen good results to speak of them." He used his observations of Scott's Troop L as evidence. The men of the troop, from the Apache, Comanche, and Apache tribes, entered the service three years prior as "the usual blanket Indians," however, military service changed all that. Completion of their military service allowed the soldiers to return to their tribes, where their influence became significant and positive. Having become conversational in English, made aware of the benefits of cooperating with the federal government, disciplined, and exposed to responsibility, Glennan called the incorporation of Native Americans into organized army units the "strongest hold the Government has ever had on these tribes."

Death Although Glennan was retired on March 2, 1926, he was activated two days later in order to supervise construction work being done on Walter Reed and served in this capacity until his death on December 24, 1927. He amassed an extensive collection during his lifetime. After his death, a large portion of it was donated to the Smithsonian Institution in the 1940s by Frances Glennan. Over seventy artifacts representing the Kiowa, Comanche, Apache, Cheyenne, Blackfoot, Pueblo, along with a number of other Native American cultures, are currently housed at the National Museum of Natural History.

Family Glennan never married during his lifetime. Despite remaining single, he was nonetheless considered a "handsome man" with "many attractive qualities."
