Born at Carrollton, Ohio on February 19, 1855, Crozier was the son of Robert Crozier, Chief Justice of Kansas in 1863–1866, and a United States Senator from that state from December 1873 to February 1874. William Crozier married Miss Mary Hoyt Williams in England on October 31, 1913; the only daughter of Mrs. Elizabeth Hoyt Williams and the late Charles Augustus Williams of New London and Washington, and the sister of the Hon. William C. Williams, commissioner of immigration at Ellis Island. General Crozier is buried in Arlington National Cemetery Section East Site S-28 with his wife Mary Williams Crozier. Crozier graduated at West Point in 1876, was appointed a second lieutenant in the 4th Artillery, and served on the Western frontier for three years against the Sioux and Bannock Indians.
Work
From 1879 to 1884 Crozier was instructor in mathematics at West Point, and was superintendent of Watertown Arsenal from 1884 to 1887. In 1888 he was sent by the War Department to study recent developments in artillery in Europe, and on return he was placed in full charge of the construction of gun carriages for the army. With General Adelbert R. Buffington, a future chief of ordnance, he invented the Buffington–Crozier disappearing gun carriage. He also invented a wire-wound gun, and perfected many appliances connected with heavy and field ordnance. In 1890 Crozier made captain. During the Spanish–American War he was inspector-general for the Atlantic and Gulf coast defenses. In 1899 he was one of the American delegates to the Peace Conference at the Hague. He later served in the Philippines on the staffs of Generals John C. Bates and Theodore Schwan, and in 1900 was chief of ordnance on the staff of General Adna Chaffee during the China Relief Expedition. In November 1901 he was appointed brigadier-general and succeeded General Buffington as Chief of Ordnance of the United States Army. He served until 1918, not counting the time he was president of the Army War College in 1912 and 1913. The provision of munitions in World War I was under his charge until December 1917. He was then made a member of the Supreme War Council, and in the discharge of this office was in Prance and Italy for the first half of 1918. Crozier presided over adoption of the M1911 and the obscure M1909 Benét-Merciélight machine gun, as well as the replacement of.30 Army Gatling Guns. He also oversaw and authorized donation and sale of various condemned cannon for use in town centers, soldier's monuments, and posts for fraternal organizations such as the Grand Army of the Republic. His Notes on the Construction of Ordnance, published by the war department, were used as text-books in the schools for officers, and he also authored several other important publications on military subjects. Crozier also presided over the adoption of the M1903 rifle, the M1918 BAR, and the M1917 machine gun, all of which would serve well into the latter half of the 20th century. He also played a role in the rejection of the Lewis Gun by the Army, although it was quickly adopted by the British and used effectively through both World Wars. A few were used by the United States Marine Corps, and eventually, by the Army to a limited degree. He died at age 87 in 1942.
Gantt chart
In 1917, after inspection of factories in which Henry Gantt had installed his methods, Crozier, then Chief of Ordnance, retained Gantt as a consultant on production, first at the Frankford Arsenal, and then, immediately after the declaration of war, in the Ordnance Department at Washington. Large orders had been placed with arsenals and other manufacturing plants for the production of arms and munitions, but it was difficult to get a comprehensive idea of what progress was being made in the filling of these orders. Quantities had suddenly jumped from hundreds to millions, and it was impossible to convey by means of typewritten tables the significance of such unusual quantities or the time necessary to produce them. Charts of the usual type were unsatisfactory because they did not sufficiently emphasize the time and because of their bulk, since only one item could be put on a sheet. Gantt concentrated on developing charts which would show a comparison between performance and promise. Several years previous to this time, he had used a chart on which the work for machines was "laid out" according to the time required to do it. The Gantt Progress Chart, as developed from this early form, was found to help in the making of definite plans and to be highly effective in getting those plans executed. The rate at which the work goes forward is continuously compared with the advance of time, which induces action to accelerate or retard that rate. These charts are not static records of the past: they deal with the present and future and their only connection with the past is with respect to its effect upon the future. Crozier quickly grasped the possibilities of this chart in helping to fix responsibility for action or lack of action, and had it introduced in various branches of the Ordnance Department. During 1918 these charts were used in the United States arsenals, in the production of naval aircraft, and in other government work, such as that of the Emergency Fleet, the Shipping Board, etc.
Memorials
On his death, he bequeathed to the Philadelphia Museum "The Crozier Collection", of antique crystal, porcelain and china. On her death, Mary Williams Crozier left $300,000 to West Point to build a memorial hall. The USMA rejected her chosen building site, and the bequest reverted to another institution.
