John "Jack" Marshall Lee is an American mathematician, specializing in differential geometry. Lee graduated from Princeton University with a bachelor's degree in 1972 became a systems programmer and a teacher at Wooster School in Danbury, Connecticut in 1975–1977, he continued his studies at Tufts University in 1977–1978. He received his doctorate from Massachusetts Institute of Technology in 1982 under the direction of Richard Melrose with dissertation Higher asymptotics of the complex Monge-Ampère equation and geometry of CR manifolds. From 1982 to 1987 Lee was an assistant professor at Harvard University. At the University of Washington he became in 1987 an assistant professor, in 1989 an associate professor, in 1996 a full professor, his research deals with, among other topics, the Yamabe problem, geometry of and analysis on CR manifolds, differential geometry questions of general relativity. In 2012 he received, jointly with David Jerison, the Stefan Bergman Prize from the American Mathematical Society.

Lee created a mathematical software package named Ricci for performing tensor calculations in differential geometry. Ricci, named in honor of Gregorio Ricci-Curbastro and completed in 1992, consists of 7000 lines of Mathematica code; the software package is distributed via the Internet and was chosen for inclusion in the MathSource library of Mathematica packages supported by Wolfram Research.

Sir Peter Teazle was a good British bred Thoroughbred racehorse, a Leading sire in Great Britain & Ireland nine times, carried on the sire line of Herod. Bred by Edward Smith-Stanley, 12th Earl of Derby, Sir Peter Teazle was by the undefeated Highflyer. Sir Peter's sire, Highflyer was on the Leading Sire list 16 times, producing 469 winners, seven of which won classic races. Highflyer got the mare Prunella, the sons Delpini and Traveller, his dam, was by Snap, himself on the Leading Sire list four times and a great producer of raw speed. Papillon had some success as a racehorse, finishing third out of 22 in the 1773 Craven Stakes, losing to Firetail and Miss Timms. Sir Peter was her 7th out of 12 living foals, one of several winners she produced, including the filly Lady Teazle, second in The Oaks and won 11 races during her career; the name comes from a character in the classic comic play The School for Scandal. Sir Peter first came to the track at three, continued the season undefeated, he won The Derby at his first start, a sweepstakes at Ascot, the 1,000 Guineas subscription race for his age group, the Prince of Wales's Plate, before beating Bullfinch in a 500 guineas match and winning again against Bullfinch by forfeit for a second match.

He won a 40 guineas subscription purse and a sweepstakes by walkover. At age four at Newmarket First Spring he won the Jockey Stakes, the rich Claret Stakes, the Fortescue Stakes, twice beating Buzzard, received a compromise in a scheduled match against Mentor. At Newmarket July he won the Grosvenor Stakes over two miles. In October at Newmarket he received, he suffered his first defeat, in a 500 guineas match against the Duke of Queensberry's four-year-old Florizel colt, giving Dash 32 pounds in weight. His final race of the year was a 300 guineas match against the good mare Maria, he was his only loss one in which he was conceding gobs of weight. His luck turned, losing a 500 guineas match to Dash —who was carrying 32 lbs. less in weight—although this was because Sir Peter was pricked during shoeing, had to take several days off work before the race. He defeated Maria in a 300 guineas match, he finished his four-year-old season with seven wins from eight starts. Sir Peter won the Newmarket Craven, beating Meteor again.

He forfeited two races—a six-mile, 1,000 guineas match against Dash, 500 guineas match against Meteor—probably due to physical problems. Sir Peter lost to Mulberry, carrying 28 lbs less, over the four mile Beacon course at Newmarket, he broke down in a race, was retired to stud. Sir Peter stood at Derby's Knowsley Stud in Lancashire, where he had great success in the breeding shed. During this time, he sired a Doncaster Cup, four Epsom Derby winners, two Epsom Oaks winners, four St. Leger winners, finished his career as the Leading Sires list nine times, his sons Walton and Sir Harry would be top on the list, Walton in Britain for two years, Sir Harry in the US. His top offspring include: Agonistes: won the Richmond Cup, others, 3rd in St. Leger Archduke: 1796 colt, won the Derby 1799. Ambrosio: 1793 colt, won 18 races including the St. Leger in 1796, the Newmarket Craven Oatlands twice, the Newmarket's Jockey Club Plate, the Great Subscription Purse at York. Barbarossa: 1802 colt, won the Egremont Stakes at Brighton, the Somerset Stakes, several Kings Plates.

Beatrice: 1791 filly, dam to Vicissitude Caleb Quotem: 1802 colt, won the Doncaster Cup, 2nd in the St. Leger Cecilia: 1793 filly, won at Chesterfield. Dam to Whitenose. Ditto: 1800 colt, won the Derby in 1803, the Claret Stakes at Newmarket, Newmarket's Craven Stakes, the King's Plate at Guildford. Sired Luzborough Expectation: won the Ladies' Plate at Lewes Fyldener: 1803 colt, won the St. Leger in 1806 in addition to six other races, grandsire of Swallow Haphazard: 1797 brown colt, a good racehorse, sire of Filho da Puta, Reginald and Figaro. Hermione: 1791 mare by Florizel, won 21 races, including the Oaks Houghton Lass: 1801 filly, 2nd twice in Newmarket's Oatlands Handicap stakes, 2nd in the Somerset Stakes at Brighton. Dam to Oaks winner Oriana, Ashton.
