skeptical, repeating how solidly built the towers were, but he did not finish his sentence before the South Tower (Tower Two) started to collapse. Clark and Praimnath had left the South Tower just three minutes before it collapsed; they were two of the last 25 people to exit the building; Clark was number 22. Only two other people exited the South Tower after Clark and Praimnath. Aftermath Praimnath thanked Clark for saving his life. Clark, in turn, also thanked Praimnath since he felt that the act of leaving his group and freeing Praimnath drew him out of a debate that might have ended with his joining the others who went up to their deaths. His Euro Brokers colleague, Ron DiFrancesco, who had initially turned around because of the smoke, mustered the strength to resume the descent and was the last person to escape the South Tower before its collapse; he awoke several days later in a hospital, suffering from extensive burns and a head laceration. They were among only four people who managed to escape from in or above the impact zone in Tower 2. Richard Fern, a Euro Brokers IT manager, was the fourth. Sixty-one of Clark's co-workers were killed in the attack. Clark was later appointed by his company's management to be President of the Euro Brokers Relief Fund, created to help take financial care of the families of those who were lost. He retired in 2006, a year after Euro Brokers merged with another company. Since his retirement, he has been volunteering with various non-profit organisations, including serving on the board and as treasurer of the New Brunswick Theological Seminary in New Jersey. In popular culture Clark's and others' stories were told on the BBC docudrama 9/11: The Twin Towers (2006, a.k.a. Inside the Twin Towers). His story is also chronicled on the documentary United by 9/11 (2006).
