Robert Heysham Sayre (October 13, 1824 – January 4, 1907) was vice president and chief engineer of the Lehigh Valley Railroad. He was also vice president and general manager of Bethlehem Iron Company, precursor of Bethlehem Steel Corporation. The town of Sayre, Pennsylvania was named in his honor.
Sayre was born on October 13, 1824 to William Heysham Sayre and Elizabeth Kent, his wife, on the Kent family's farm near Bloomsburg in rural Columbia County, Pennsylvania. In 1828, the Sayre family moved to Mauch Chunk (now Jim Thorpe), Pennsylvania where William worked for the Lehigh Coal & Navigation Company as a lockmaster. As a result of observing the locks, young Robert showed an early interest in construction and civil engineering.
Sayre was one of the founders of Bethlehem Iron Company, precursor of Bethlehem Steel Corporation. He was responsible for the design and construction of the company's first iron works during the years 1861 through 1863. He became vice president of Bethlehem Iron Works in 1891.
Sayre built a large house in Bethlehem and lived in it from 1858 until his death in 1907. Currently his house is known as the Sayre Mansion, and is in use as a bed-and-breakfast.
