PUSEY, Caleb, colonist, born in Berkshire, England, about 1650; died in Chester county, Pennsylvania, 25 February, 1727. He was educated as a Baptist, but subsequently became a Quaker, and was of Penn's company that came to Pennsylvania in 1682. Before leaving England he united with Penn and a few others in forming a "joint concern" for the "setting up" of mills in the new province, of which concern Pusey was chosen the manager. He caused the framework to be prepared and shipped in the "Welcome," and in 1683 erected on Chester creek, near what is now Upland, Pennsylvania, the famous mills known as the "Chester Mills," which were the first in the province under Penn's government. Penn himself attended at the laying of t, he corner-stone. Pusey managed the mills for many years, and came finally to own them conducting an extensive milling business until his death. He held a high place in civil affairs, was engaged in laying out roads and negotiating with the Indians, and for two years was sheriff of Chester county. For many years he was a justice of the peace and of the county courts, and an associate justice of the supreme court, serving also for ten years or more in the assembly, and for more than" a quarter of a century in the supreme or provincial council. His name constantly appears m the minutes of the Society of Friends among those who were most active in settling difficulties and in promoting deeds of benevolence. He frequently appeared in the ministry, and as a controversialist and a writer was one of the ablest and most noted of his sect in his day. His reply to Daniel Leeds was liberally subscribed for by the meetings, and widely circulated. He was an intimate friend of George Keith, but, when the latter attacked the Quaker doctrines, Pusey was active among those who pronounced against him. From Pusey, Smith, the early historian, obtained much of the material from which he made up his manuscript history, which formed the basis of Robert Proud's "History of Pennsylvania." In 1697 Pusey was chosen by the Quakers to be one of the committee to examine all books that the society proposed to publish, which post he held till his death. Among his published writings are "A Serious and Seasonable Warning unto all People occasioned by two most Dangerous Epistles to a late Book of John Fall-doe's." addressed to the people called Anthony Palmer's Church (London, 1675); "A Modest Account from Pennsylvania of the Principal Differences in Point of Doctrine between George Keith and those of the People called Quakers" (1696);"Satan's Harbinger encountered; His False News of a Strumpet detected," etc., a reply to Daniel Leeds's " News of a Strumpet" (Philadelphia, 1700); "Daniel Leeds justly rebuked for abusing William Penn, and his Folly and Falsehoods contained in his Two Printed Challenges to Caleb Pusey made Manifest" (1702) ; " George Keith once more brought to the Test, and proved a Prevaricator" (1703); "Proteus Ecclesiasticus, or George Keith varied in Fundamentals" (1703); "The Bomb searched and found stuff'd with False Ingredients, being a Just Confutation of an Abusive Printed Half-Sheet, call'd a Bomb, originally published against the Quakers, by Francis Bugg" (1705); "Some Remarks upon a Late Pamphlet signed part by John Talbot and part by Daniel Leeds, called "the Great Mystery of Pox-Craft" (1705)" and "Some Brief Observations made on Daniel Leeds, his Book, entitled "The Second Part of the Mystery of Fox-Craft'" (1706). For a fuller account of the titles of these works see "Issues of the Pennsylvania Press, 1685-1784," by Charles R. Hildeburn (1885). The imprint of Pusey's works, excepting the first two and the last, bear the name of Reynier Jansen.
