In 1920, in the year that Jack J Janssen was born, in September, a bomb exploded in the J.P. Morgan bank building in New York City, killing 30 people immediately - 8 later died due to their injuries - and injuring another 200. Killing more people than the 1910 bombing of the LA Times (the deadliest terrorist act up until then), no one took responsibility and the perpetrators were never found. Italian anarchists were suspected of the bombing.

The same summer, there were riots in Beaumont, Texas and Harlem, New York.

In 1961, at the age of 41 years old, Jack was alive when on August 13th, East Germany began erection of what would become the Berlin Wall between East and West Berlin.
