Known as the "father of VPI," John McLaren McBryde (January 1, 1841-March 20, 1923) was the fifth president of Virginia Agricultural and Mechanical College and Polytechnic Institute (VPI, or Virginia Tech). He was born in Abbeville, South Carolina, to Susan McLaren and John McBryde, a Scottish cotton merchant. In December of 1858, John McLaren McBryde enrolled in South Carolina College (later the University of South Carolina) in Columbia, South Carolina. He later transferred to the University of Virginia in 1859, leaving in 1861 to fight in the American Civil War for the Confederacy. Having joined the military, McBryde was stationed on both Sullivan and Morris Islands, reportedly seeing the first shot fired on Fort Sumter. In 1862, McBryde contracted typhus fever and was forced to leave the army, but went on to work for the Treasury Department of the Confederate States of America in Richmond, Virginia.

Following the end of the Civil War, McBryde ran a large farm named Branchland in Charlottesville, Virginia. During this time, he published numerous articles on the subject of agriculture, gaining him the attention that eventually lead to his appointment as a Professor of Agriculture and Botany at the University of Tennessee in 1879. In 1882, McBryde was offered a chair at the South Carolina College, where he remained until 1891, expanding it into a university after becoming president. In 1891, South Carolina University was again reduced to a college and its agricultural department moved to Clemson, leading to McBryde's acceptance of the Presidency at the Virginia Agricultural and Mechanical College (VAMC).

During his time at Virginia Tech, McBryde divided the college into separate departments, expanded the curriculum, oversaw the installation of an infirmary and a new water system, added dormitories and faculty housing, and increased enrollment from 135 students in 1891 to 727 by 1903. After his retirement in 1907, McBryde was the first person elected president emeritus for the college, eventually becoming known as "the father of VPI."

On November 18, 1863, McBryde married Cora Bolton. They had eight children, six of whom lived to adulthood: Janet (1864-1869), James (1866-1925), Anna (1868-1948; later Mrs. Robert J. Davidson), John McLaren, Jr. (1870-1956), Charles (1872-1962), Susan (1874-1951), Meade (1877-1959), and Waid (abt. 1878-?). John Bolton McBryde is the grandfather of Polly Ashelman.

In 1923, McBryde died at his son's home in New Orleans but was returned to Blacksburg, Virginia for burial.
