He waived his right to exemption, which he said would make his American citizenship be granted more quickly; however, the war was over before he was called up to military service.
In 1921–23, he invented a mechanical breast pump, which saved many premature infants' lives and made Lasker much money, although it caused his friends to refer to him facetiously as "the chest player".
Lasker wrote that had he won the game against a leading Berlin amateur, his opponent would likely have told him, "You are just lucky!
He first read about it in a magazine article by Oskar Korschelt which suggested Go as a rival to chess, a claim that he found amusing.
[8] Later on his interest was piqued again when he noticed the record of a Go game on the back of a Japanese newspaper being read by a customer of a cafe where they played chess.
This experience led them to a deeper appreciation for the game, and they studied it in earnest, but were unable to interest other chess players.
[10] After two years, Emanuel Lasker, then the world chess champion, returned to Germany from the United States.
The Laskers took a nine-stone handicap, and played in consultation with each other, considering their moves deeply, but their opponent beat them effortlessly and without taking much time to think.
He was, however, given permission to travel to the United States by Sir William Haldane-Porter, who was head of what would become the UK Immigration Service.
Haldane-Porter remembered that Lasker had won the London chess championship in May 1914 and he had personally witnessed Edward's famous game against George Alan Thomas that same year.
Edward Lasker was instrumental in developing Go in the U.S., and together with Karl Davis Robinson and Lee Hartman founded the American Go Association.
Samuel Lasker moved to another Polish village, Kępno, in 1769, after it had been captured by Frederick the Great and became a German township, and I am the last descendant of his who was born there.
His first-born son left Kepmen [sic-Kempen] and moved to Jarotschin, another Polish village, and Emanuel Lasker was that one's greatgrandson.
