Who was Leslie Richard Groves?
Leslie Richard Groves (1896–1970) was a U.S. Army officer who headed the Manhattan Engineer District, also known as the Manhattan Project, which handled all aspects of the creation of the atomic bomb.
Groves, the son of an army chaplain, was born in Albany, New York. He went to the University of Washington, the Massachusetts Institute of Technology, and the United States Military Academy at West Point. Groves oversaw all army construction in the United States from 1940 to 1942, during the mobilization for World War II.
In mid-1942, he was chosen to head the U.S. atomic bomb project. He oversaw plant construction for the production of uranium and plutonium. Groves also picked the location and staff for the Los Alamos laboratory in New Mexico. He retired from the army in February 1948 and took a job with Remington Rand.

How did Leslie Groves' leadership affect the outcome of World War II?
Leslie Groves directed the Manhattan Project, which oversaw all aspects of research, production, and security for the creation of the atomic bomb. He was responsible for constructing plants and factories to produce key atomic bomb materials and chose the site and personnel for the Los Alamos laboratory in New Mexico.
Groves also managed security, intelligence, and counterintelligence operations and became involved in high-level domestic and international policy issues. He modified B-29 aircraft to carry the bombs and initiated a special air force unit to deliver them.
The atomic bombs dropped on Hiroshima and Nagasaki led to Japan's agreement to Allied surrender terms. Some historians argue that these bombings led to the end of World War II.

Leslie Richard Groves (born August 17, 1896, Albany, New York, U.S.—died July 13, 1970, Washington, D.C.) was an American army officer in charge of the Manhattan Engineer District (MED)—or, as it is commonly known, the Manhattan Project—which oversaw all aspects of scientific research, production, and security for the invention of the atomic bomb.
Groves was the son of an army chaplain and grew up on military posts throughout the United States. He attended the University of Washington at Seattle for one year and the Massachusetts Institute of Technology at Cambridge, Massachusetts, for two years before entering the United States Military Academy at West Point, New York, in June 1916. In an effort to supply more officers to American forces in Europe, several West Point classes were accelerated. Groves graduated on November 1, 1918, 10 days prior to the armistice ending World War I. He ranked fourth in his class and chose the Corps of Engineers as his branch. For the next 20 years, he was assigned various engineering duties throughout the United States and Hawaii. He also attended Engineer School, the Command and General Staff School, and the Army War College, completing the schooling of those expected to hold high command and staff positions. During the mobilization period for World War II, from 1940 to 1942, Groves eventually oversaw all army construction in the United States, a mammoth task involving building camps, munitions plants, airfields, depots, and the Pentagon to support an army that grew from 135,000 during the interwar period to an eventual 8,000,000 during World War II.
In mid-1942, the Army Corps of Engineers was put in charge of the U.S. atomic bomb project—known as the Manhattan Engineer District (MED) or Manhattan Project—and Groves was selected as its head on September 17, 1942. Over the next three years, his responsibilities grew considerably. First, he oversaw the construction of plants and factories to make the key atomic bomb materials—highly enriched uranium and plutonium. He also chose the site and the key personnel for an isolated laboratory at Los Alamos, New Mexico, to research, develop, and fabricate the bomb. To ensure secrecy, he oversaw a vast security, intelligence, and counterintelligence operation with domestic and foreign branches. He became involved in many key high-level domestic policy issues and in several international ones as well. To prepare for the combat missions, he had several dozen B-29 aircraft specially modified to carry the five-ton atomic bombs, initiated the creation of a special air force unit (known as the 509th Composite Group) to deliver them, and saw to establishing a domestic training base at Wendover, Utah, and an overseas staging base at Tinian, an island north of Guam in the Pacific Ocean. These actions put Groves at the centre of the planning, targeting, and timing of the attacks on Hiroshima and Nagasaki in August 1945.
On December 31, 1946, Groves turned over the MED to the civilian Atomic Energy Commission, created by the Atomic Energy Act of 1946. After a final assignment as chief of the Armed Forces Special Weapons Project, he retired from the army in February 1948 and took a position with Remington Rand. He wrote Now It Can Be Told (1962), describing his experience of running the Manhattan Project.
