Alexander Biddle was educated at the University of Pennsylvania and worked with his father until the start of the Civil War. He served in the 121st Pennsylvania Volunteer Infantry and saw action at the battles of Fredericksburg, Gettysburg (under General Abner Doubleday), Chancellorsville and the battle of Bristoe Station. After the war be became a director of the Pennsylvania Railroad and the Philadelphia Savings Fund Company. He was instrumental in organizing the Ridgway Library which is part of the library company of Philadelphia. Another unsung American hero who rightly deserves our thanks this Memorial Day Weekend.
