Captain Abram Epperson Wood (September 4, 1844 – April 14, 1894) was an officer in the United States Army between 1872 and 1894, and the first acting Military Superintendent of Yosemite National Park.

Wood mustered out at Louisville, Kentucky, on July 21, 1865, as second lieutenant of Company F.[3] He returned to Iowa, where he received three years of preparatory education for the academic rigors of the United States Military Academy.

[2] Wood entered the U.S. Military Academy at West Point, New York, on July 1, 1868 at the age of twenty-three under a special Congressional dispensation, graduating 14th in order of merit in a class of 57 on June 14, 1872.

While at Fort Clark, he participated with the 4th Cavalry on extended campaigning in the field between June 1873 and May 1874 seeking to stop Kickapoo and Apache incursions into Texas from Mexico.

On September 21, 1878, at Little Sandy Creek near present-day Ashland, Kansas, Wood led his company in a mounted charge to rescue two wounded cowboys ambushed and trapped in a small canyon.

Lewis attacked on the late afternoon of September 27, 1878, using dismounted cavalry including Wood's company in skirmish lines, and temporarily succeeded in pinning down the Cheyenne in the canyon.

In May, 1881, Wood's company was part of an expedition that moved the Uncompaghre Utes to the new Ouray Agency in Utah, and then continued to Arizona to quell an outbreak of hostilities with Apaches, before being posted to Fort Stanton, New Mexico, on November 17.

United States Secretary of the Interior John W. Noble requested Harrison to provide troops "to prevent timber cutting, sheep herding, trespassing, or spoliation in particular.

[13] After posting notices, Wood arrested and evicted trespassers from the park, but this tactic largely failed to deter sheepherders when the United States Attorney for the Northern District of California publicly declared that he would not prosecute violators.

The process of recovering their dispersed herds was time-consuming and uneconomical to the trespassers, and the problem of overgrazing in the park was brought under control until the sheepherders devised counter tactics after 1895.

[12] Wood died at the Presidio, San Francisco, California on April 14, 1894 at the age of forty-nine, following surgery to remove cancerous tumors of the tongue and throat attributed to his fondness for smoking.
