One day while doing door-to-door market research, this guy knocks on a door and is greeted by a beautiful young housewife.

Died 29 Oct 1956 at age 90 (born 11 Feb 1866).Friedrich C. Hofmann was a German chemist who polymerized isoprene to create synthetic rubber (1909) while working as a senior chemist for Elberfelder Farbenfabriken vorm. Friedr. Bayer & Co.

Hofman also studied the polymerization of butadiene and 2,3-dimethyl butadiene.«
