John Pierpont "Autographs of Freedom" (1853). John Pierpont did not write the song "Jingle Bells" as erroneously claimed by Robert Fulghum in his collection of essays It Was on Fire When I Lay Down on It (1989). "Jingle Bells" was composed by his son James Lord Pierpont, who lived in Savannah, Georgia, and who was a Confederate soldier during the Civil War, composing songs for the Confederate States of America, including "Our Battle Flag", "Strike for the South", and "We Conquer or Die". John Pierpont was also the maternal grandfather of financier J. Pierpont Morgan. For detailed genealogical information, see 20>16232 in
Pierpont prime that can be constructed with a compass, straightedge, and angle-trisector. Regular polygons which can be constructed with only compass and straightedge (constructible polygons) are the special case where and is a product of distinct Fermat primes, themselves a subset of Pierpont primes. In 1895, James Pierpont studied the same class of regular polygons; his work is what gives the name to the Pierpont primes. Pierpont generalized compass and straightedge constructions in a different way, by adding the ability to draw conic sections whose coefficients come from previously constructed points. As he showed, the regular -gons that can be constructed with
