Samuel Leeds Allen
Allen's revolutionary sled was developed and tested at Westtown School and Ivystone. Stokes Hill, a popular sledding area located next to Breidenhart, Allen's Moorestown home, has been mistakenly identified as the birthplace of the Flexible Flyer sled. However, Allen built Breidenhart in 1894, five years after the Flexible Flyer was introduced.
Allen was awarded almost 300 patents for a wide range of farming machinery, including the fertilizer drill, seed drill, potato digger, cultivator, furrower, pulverizer, grass edger and numerous other farm implements. In order to provide year-round employment for his workers producing farm equipment, Mr. Allen sought to create a product that could be sold during the winter. His passion for sledding led him to develop a series of sleds and sled improvements. Allen was issued U.S. Patent number 408,681 on August 13, 1889 for the Flexible Flyer.

- DeCou, p. 101: "Ivystone formerly the home of Samuel L. Allen, now owned by Harry Shea, historically speaking is the most interesting building in or near Westfield. This old homestead stands on or very near the site of the first house erected by Thomas Lippincott in 1711. The western end which is the frame part was erected about 1756 and the eastern end built of native Sandstone in 1800."
