Count Hans Brühl

Count Hans Brühl was born in Wiederau, Germany on 12/19/1736. He became Minister of Saxony but lived in London. He was interested in music and astronomy, even built an observatory. It's quite likely that he originally met Philidor through their mutual interest in music, but he was also a fairly strong chess player and a regular opponent of Philidor. 20 of the 30 games of Brühl that have survived were played againt Philidor (which may also be the very reason they survived) He died in London on 6/9/1809
In 1782 Philidor played a 2 game blindfold simul with Count Brühl and Thomas Bowdler. In 1783 Philidor,played a 2 game blindfold simul with Count Brühl (and Thomas Bowdler and possibly George Atwood).

Thomas Bowdler

Thomas Bowdler was born in 1754 and died in 1825. It seems he was a doctor and frequented the Strand club on St. James, where he was considered one of the strongest players. He contested Philidor in several games. In his 3 game blindfold simul of 5/08/1783, Philidor won 2 and drew 1. Bowdler's was the drawn game after 51 moves (and 1 hour and 45 minutes) Philidor had the black peices in all three games - the 2 wins were even odds but in Bowdler's game, Philidor removed his f7 pawn.
Bowdler played against Philidor in another blindfold simul on 5/28/1783 and won. It's uncertain if this game was even or not. Bowdler played Philidor in a match of 5 games in April of 1788. Philidor gave him odds of the f7 pawn and the move. Bowdler won 1, lost 2, drew 2. Bowdler played Philidor one more time in 1789. Philidor gave him odds of the f7 pawn, but not the move, and won in 40 moves. Unfortunately, Bowdler also attained a different sort of fame. According to Wikipedia he had become (in)famous as the editor of a children's edition of William Shakespeare, the Family Shakespeare, in which he "endeavoured to remove every thing that could give just offence to the religious and virtuous mind." and His name lives on in the eponym bowdlerization (adjective bowdlerized), to describe the process of censorship by arbitrary deletion of "objectionable" material from a work of literature to "purify" it, rather than banning the work outright.

Other players who either player Philidor or were at least contemporaries include:

Henry Jennings (1731-1819), a renowned collector of Art. in 1777 he eloped with Elizabeth Katherine Nowell, and took her surname, Nowell, as his in order to be eligible for her inheritance.

Frances Maseres, a lawyer who produced 20 books on mathematics, history and other subjects.

Field-Marshal Henry Seymour Conway (1721-1795), patented a type of a furnace for the use of brewers and distillers and wrote essays.

Richard Twiss (1747-1821), an English writer who made 16 sea voyages, recording what he saw. While his travel books weren't particularly well received, his book, Chess, published anonymously in 1787 (with a second volume published in 1789), and it's later supplement, Miscellanies, published in 1805 were a Compilation of all the Anecdotes and Quotations that could be found relative to the game of Chess; with an account of all Chess-books that could be procured.
