Henry Howard Houston II (1895-1918) was the son of a prominent Philadelphia family, the Houstons. He enjoyed a privileged upbringing, graduating from Chestnut Hill Academy in 1912 and from the University of Pennsylvania in 1916. Upon his graduation date, he enlisted in Battery C of the First Field Artillery, Pennsylvania National Guard, and was sent to the Texas and New Mexico borders in response to Pancho Villa's raids from Mexico. In January 1917, he volunteered with the American Field Ambulance Service in France during World War I, stationed near Verdun, where he was constantly under fire when performing his duty to pick up wounded soldiers from the trenches. Henry took a commission in the French Army and enrolled in its transportation school. The French government awarded him the Croix de Guerre for gallantry under fire. When the U.S. entered the war, Henry resigned his commission in the French army and rejoined the Pennsylvania National Guard, his unit being the 53rd Field Artillery Brigade, 28th Division. He returned to the U.S. and received training as an aerial observer at Fort Sill, Oklahoma. Early in 1918 he returned to France as a staff member of the 53rd Field Artillery Brigade, commandedn by General William Price. In August 1918, Lt. Houston was killed south of Arcis-le-Ponsart while returning from an air field. He was 23. The bulk of this eight linear feet collection reflects Henry's personal life as a son, soldier, friend and lover, during the last three years of his life 1916 to 1918.

The Smith-Houston-Morris-Ogden Family Papers document the history of the Houston, Smith, Ogden, Morris and allied families, beginning in the late 17th century, and continuing through to near the end of the 20th. Among the many treasures in this vast collection are the papers of Pennsylvania Railroad executive Henry Howard Houston (1820-1895), his son, Samuel Frederick Houston (1866-1952), and of Pennsylvania attorney and treasury official, William Meredith (1752-1816). Although the collection contains a great deal of interest with respect to land speculation, commerce, and trade emanating from Philadelphia, the bulk of the Smith Family Papers consists of personal and family correspondence and other papers. Among the largest and most interesting bodies of papers are those of L.M.C. Smith and Eleanor Houston Smith, daughter of Samuel F. Smith. These document the family's progressive attitudes regarding and resource conservation, historic preservation, and their social activism. This very large collection includes much material that is not itemized below.
