David was born on March 24, 1845 in Richland, now the borough of Mount Joy, Lancaster County, Pennsylvania, United States. His father, Jacob Stauffer, a patent lawyer and naturalist of reputation, was a descendant of John Stauffer, who emigrated from Switzerland to Pennsylvania in 1710; his mother, Mary Ann Knox McNeely, was of a Scotch-Irish family that settled in Pennsylvania about 1721.
Graduating from the high school at Lancaster in 1862, at the head of his class, David was granted a scholarship in Franklin and Marshall College, but on September 12, 1862, enlisted for service in the Civil War and saw action almost at once in the Antietam campaign.
Early in 1864 Stauffer was appointed a master's mate in the United States Navy and ordered to the Alexandria in the Mississippi Squadron under Rear Admiral David Dixon Porter.
As mate he later commanded the same vessel, in May 1865 he was listed as acting ensign, and on November 1, 1865, was honorably discharged. At once he began his engineering career as rodman on surveys for the Columbia & Port Deposit Railroad in eastern Pennsylvania. He continued on surveys and construction work successively as assistant engineer of the Philadelphia & Reading Railroad and division engineer of the Allentown Railroad from 1868 until 1870, when the boom in railroad construction collapsed.
Subsequently, from August 1870 until its completion in February 1876, he served as assistant engineer and consultant in the construction of the South Street Bridge over the Schuylkill River, Philadelphia. In this work he used compressed-air caissons in sinking foundations, a method which at the time was comparatively new to the United States, and his paper, "The Use of Compressed Air in Tubular Foundations", based on study of the French and English practice, was used for a time as a textbook in several engineering schools. A fuller description of the work at South Street Bridge was published after its completion in the Transactions of the American Society of Civil Engineers (vol. VII, 1878).
Meanwhile, as assistant chief engineer on the Bound Brook line of the Philadelphia & Reading Railroad, Stauffer had special charge of the construction of the Delaware Bridge, and upon its completion, June 1, 1876, he engaged in private practice, during which he made bridge plans for the City of Philadelphia.
Beginning on April 15, 1877, he was construction engineer for the Philadelphia Water Department, building the Frankford reservoir and pumping stations. Late in 1879 with the contractor R. A. Malone, he undertook the construction of the Dorchester Bay sewage tunnel at Boston, an inverted siphon some 9, 000 feet long, with a bottom 180 feet below sea level. The seepage through the rock roof was so great that an enormous pumping plant involving large expense was necessary. The engineering problems he encountered are described in Stauffer's paper, "Shaft Sinking Under Difficulties at Dorchester Bay Tunnel".
In December 1880, when the tunnel was nearly finished, he sold his interest in the contract to his partner, returned to Philadelphia, and was associated with the Philadelphia Bridge Works until September 1882, when he resigned and opened an office in New York as consulting engineer.
In January 1883, he bought an interest in Engineering News, with which he was connected in an editorial capacity until he sold his interest in 1907.
He died at his home in Yonkers.
David McNeely Stauffer designed a number of bookplates. Many of the illustrations in Engineering News were from his pen. Early in his career he began a collection of thousands of prints illustrating the first four centuries of the art of engraving on wood and copper, and in his later years this hobby absorbed most of his time and energy. His work American Engravers upon Copper and Steel (2 vols. ) remains a standard work in its field. He was also interested in public affairs, and was long a member of the Palisades Interstate Park Commission for the preservation of the Palisades of the Hudson River. David Stauffer was a Civil War veteran. He commanded the USS Alexandria on the Mississippi River for the Union Navy.

He was elected to the American Society of Civil engineers, became the second American to be appointed to the Royal Institute of Civil Engineers in London, England, was appointed a member of the Interstate Palisades Park Commission and was a member of the Empire State Society of Sons Of the American Revolution and president of the Yonkers Chapter. Other organizations he belonged to were the Loyal Legion, the Century Club, the Naval Order of the United States, the Union League of Philadelphia and founder of the Penn Club of Philadelphia.
On April 19, 1892, he married Florence Scribner, daughter of G. Hilton Scribner, secretary of state of New York under Governor Dix. Sadly, both their children died in infancy.
