Following his retirement from the Army, he became a prominent figure in New York society, serving in many societies, and as vice president of the American Geographical Society. The society named the Cullum Geographical Medal after him.

## Birth and early years

Cullum was born in New York City on 25 February 1809, to Arthur and Harriet Sturges Cullum. He was raised in Meadville, Pennsylvania. His father worked as a lawyer and an agent of a land company. Cullum attended the United States Military Academy, from 1 July 1829 to 1 July 1833, when he graduated third in the Class of 1833. He designed the Independent Congregational Church at Meadville and it was built in 1835–1836. The building was listed on the National Register of Historic Places.

## Pre-Civil War service

Cullum was appointed to the United States Army Corps of Engineers as a brevet second lieutenant on 1 July 1833. He served as the assistant engineer for Fort Adams in 1833. The following year Cullum served as the assistant to the chief engineer at Washington D. C., where he remained for two years. He was then involved in inspections of Forts Severn and Madison in Annapolis, Maryland, before returning to work on Fort Adams.
Cullum was promoted to second lieutenant on 20 April 1836. He supervised construction of the facilities on Goat Island until 1838. On 7 July 1838, he was made a captain. Cullum then supervised construction of Fort Trumbull in New London, Connecticut and the lower battery at Fort Griswold in nearby Groton until 1855. He also supervised a number of other projects on the East Coast from 1840 to 1864, including the repairs of sea walls at Deer, Lovells and Rainsford islands; the construction of Forts Warren, Independence, Winthrop and Sumter; the building of cadet barracks at West Point; and the construction of the United States Assay building. He later superintended engineering works on the western rivers.
Cullum was an instructor of practical military engineering at West Point from 1848 to 1851. He then served as director of the Sappers, Miners and Pontoniers at West Point. Cullum published the forerunner of his Biographical Register in 1850. He took two years leave of absence from 1850 to 1852 for health reasons, and traveled throughout Europe, Asia, Africa and the West Indies while recuperating. Cullum then returned to West Point, and taught there until 1855. When Robert E. Lee, at the time superintendent of West Point, went on a vacation to Virginia, Cullum served as acting superintendent of the Academy from 5 July to 27 August 1853.
In 1848, he introduced a type of bridge pontoon, which was used in the Mexican–American War. Cullum published Description of a System of Military Bridges, With India-Rubber Pontons in 1849.

## Civil War and later military service

On 9 April 1861, Cullum was promoted to the rank of lieutenant colonel, and shortly after to colonel. He served as an aide-de-camp to General Winfield Scott from 1 April 1861 to 1 November 1861. At the same time he was a member of the United States Sanitary Commission. Cullum was promoted to a Major in the Corps of Engineers, before becoming chief engineer of the Department of the Missouri on 19 November 1861, where he remained until 11 March 1862. Cullum then was chief engineer for the Department of the Mississippi until 11 July.
During the time, he was also the chief of staff for Henry Halleck. He was appointed brigadier general of volunteers on 1 November 1861. From 2 December 1861 to 6 February 1862, Cullum was on the board that inspected the defenses of St. Louis and the board that inspected the condition of the Mississippi Gun and Mortar Boat Flotilla. He travelled to Cairo, Illinois, where he commanded operations auxiliary to various armies in the field and also managed the defense of the District of Cairo. From February to March, he surveyed the Confederate defenses at Columbus, Kentucky.
On 6 February 1862, the Union Army under then Brigadier General Ulysses S. Grant captured Fort Henry, and ten days later, on 16 February, they captured Fort Donelson. With these victories, his forces took about 12,000 to 15,000 Confederate prisoners. The army was unprepared to handle this many prisoners and scrambled to find places to house them. Cullum sent many prisoners to St. Louis before he received War Department instructions to direct 7,000 prisoners to Camp Douglas near Chicago. Cullum was chief engineer at the Siege of Corinth.
For the rest of the Civil War, Cullum inspected or built defenses at: Cairo, Illinois; Bird's Point, Missouri; Fort Holt, Kentucky; Columbus, Kentucky; Island Number Ten; New Madrid, Missouri; Corinth, Mississippi; Harpers Ferry, West Virginia; Winchester, Virginia; Martinsburg, West Virginia; Boston Harbor; Nashville, Tennessee; the Potomac aqueduct; Baltimore; and Washington, D.C. He served on boards concerning Timby's Revolving Iron Tower, proposed military bridges, and Army Corps of Engineers officers being considered for promotion. In 1862, Cullum was appointed Chief Engineer of Halleck's armies in the Department of the Missouri.
He was Superintendent of West Point from 1864 to 1866. On 8 March 1866, President Andrew Johnson nominated Cullum to be appointed to the grade of brevet major general, USA, to rank from 13 March 1865. He was mustered out of the volunteers on 1 September 1866. In 1867, Cullum published the first edition of his Biographical Register of the Officers and Graduates of the United States Military Academy, covering all graduates from the founding of West Point to the class of 1840. The New York Times wrote that "We know of no single contribution to the military history of the Nation so rich in invaluable data and so essential to the future historian or student of American history."

## Later life and death

Cullum retired from active service 13 January 1874, with the permanent rank of colonel and the brevet rank of major general, and returned to New York City. Following his retirement, he married Elizabeth Hamilton, sister of Major General Schuyler Hamilton and the wealthy widow of Major General Henry W. Halleck.
Cullum was vice-president of the American Geographical Society, president of the Geographical Library Society of New York and a member of the board of managers of the Association for Improving the Condition of the Poor. He was also a member of the Farragut Monument Association, a delegate to the 1881 conferences of the Association for the Reform and Codification of the Law of Nations and of the International Geographical Conference, a corresponding member of the Massachusetts Historical Society, and a member of the American Historical Society and the American Academy. Cullum died on 28 February 1892 in New York City, of pneumonia. He is interred at Green-Wood Cemetery in Brooklyn.
Cullum left part of his fortune for the continuance of his Biographical Register and for an award of the American Geographical Society "to those who distinguish themselves by geographical discoveries or in the advancement of geographical science", known as the Cullum Geographical Medal. He also left $250,000 to West Point, "to be used for construction and maintenance of a memorial hall at West Point to be dedicated to the officers and graduates of the U.S. Military Academy". The building is now known as Cullum Hall. Cullum also left $100,000 for a hall for the American Geographical Society.
