Pleasant Valley, Warren County, New Jersey

In 1754, Thomas Van Horn acquired a large tract of land in the Pohatcong valley from John Moore and later built a mill on the creek. After his death, the mill was eventually bought by John Sherrerd in 1791. John's son, Samuel Sherrerd, inherited the property in 1810. Samuel's wife, Ann Maxwell, was the daughter of Captain John Maxwell and the niece of General William Maxwell, both officers in the Continental Army. Their son, John Maxwell Sherrerd, was appointed the first Surrogate of Warren County.[2][3][4] William M. Warne, husband of daughter, Susan Sherrerd, bought the property in 1833 after Samuel's death.[2] He is listed as building the main block of the house at 14 Mill Pond Road in 1834.[3]

With the completion of the Morris Canal, which bypassed Pleasant Valley and favored Washington, the area had little growth.[3] In 1865, Dr. J. V. Mattison purchased the property from the Warne family and rebuilt the mill. In 1893, William Larison bought the property. After several exchanges, the property was bought by Earle S. Eckel in 1926.[2][3]

Eckel made several changes to the property. He dredged and enlarged the mill pond, and upgraded the dam and causeway with the goal of generating hydroelectric power. After the mill burned down in 1929, he built a brick and steel power house on the old mill foundation for the turbine and generator. Eckel was also interested in aviation, in particular the autogiro by Harold Pitcairn. In 1931, he purchased one and built a runway and hangar for it, probably the first exclusive autogiro airport in America.[2][3] During National Air Mail Week, he carried mail postmarked: "Via Air Mail. First Flight. From Washington, N.J. May 19, 1938" to Newark, New Jersey using his own Pitcairn PAA-1.[5] Eckel was one of the founding members and the first vice president of the Antique Automobile Club of America in 1935.[6][7]
