During one of his engagements at the Bartholomew Fair, Pinchbeck probably met Fawkes, the cleverest sleight-of-hand performer that magic has ever known, and the two joined forces. Pinchbeck made all the automata and apparatus thereafter used by Fawkes, and, in Fawkes, he had a master-producer of his tricks. Christopher Pinchbeck never appeared on the program used by Fawkes, save as the maker of the automata or apparatus, but directly after the death of the elder Fawkes, and a few months before his own, the elder Pinchbeck appeared with the son of his deceased partner, and was advertised as doing "the Dexterity of Hand" performance. This indicates that he was inducting young Fawkes into all the mysteries of the profession at which the two elder men, as friends and business partners, had done so well. Christopher Pinchbeck was survived by two sons, Edward and Christopher, Jr. Edward, the elder, succeeded to his father's shop and regular business. He was born about 1703, and was well along in years when he entered into his patrimony, which he advertised in _The Daily Post_ of November 27th, 1732, as follows: "The toys made of the late Mr. Pinchbeck's curious metal are now sold only by his son and sole executor, Mr. Edward Pinchbeck." This announcement settles forever the oft-disputed question as to whether the alloy of copper and zinc which bears the name of Pinchbeck was invented by Christopher Pinchbeck, Sr., or by his son Christopher, Jr. All newspaper and magazine descriptions of the automata invented by the elder Pinchbeck indicate that his hand was as cunning as his brain was inventive, for they showed the most delicate mechanism, and included entire landscapes with figures of rare grace in motion.

It is said that there is only one more of these engravings extant.] "Christopher, the second son of Christopher Pinchbeck the elder," continues the biographical sketch, "was born about 1710 and possessed great mechanical ingenuity. While the elder son, Edward, was made executor and continued his father's trade in a quiet, conservative fashion, the younger son struck out along new lines and became even more famous as an inventor than his brilliant father had been.
