Richard Fuisz's meetings with Susan Lindauer ended abruptly on September 11, 2001, the day of the September 11 attacks, due to what Fuisz described as an increasingly "seditious bent" to her discussions. The September 11 attacks were a series of four coordinated terrorist attacks by the Islamist terrorist group al-Qaeda against the United States on the morning of Tuesday, September 11, 2001.

The Montreal Protocol on Substances That Deplete the Ozone Layer took effect. While unrelated to Fuisz directly, this global environmental agreement highlights the broader context of international cooperation and regulation during the period when Fuisz was active in international business.

The ARPANET officially changed to using the Internet Protocol, creating the Internet. While the text doesn't directly mention this date, it is important context considering Fuisz's later involvement in technology and the internet.

Richard Carl Fuisz was born on December 12, 1939, in Bethlehem, Pennsylvania. This marks the beginning of his life, and his birthdate is a fundamental piece of biographical information. He is an American physician, inventor, and entrepreneur.
