Brian Clark is one of the survivors of the attacks on the World Trade Center on September 11, 2001.
One of only a four people in either tower to escape from a floor above the planes' impact, Clark is noteworthy because his testimony before the 911 Commission, where he detailed problems with the 911 emergency call system, has been widely quoted.
Clark was born and raised in the Canadian province of Ontario. He attended public school in Thornhill, Ontario, and married his high school sweetheart. After graduating from the University of Toronto, he worked for a year at Euro Brokers' Toronto office. He then moved to New York City to work for Euro Brokers in the World Trade Center. He and his wife bought a house in New Jersey and raised four children. He spent 27 years working at the World Trade Center before September 11, 2001.
