Edie Lutnick, sister of Cantor Fitzgerald chief executive Howard Lutnick and their brother Gary, who died in the 9/11 attacks, has written about losing her sibling and building the Cantor Fitzgerald Relief Fund in the aftermath. All 658 Cantor Fitzgerald, eSpeed and TradeSpark staff working on the 101st to 105th floors of the World Trade Center's North Tower on 11 September 2001 were killed, representing two-thirds of the firm's New York workforce. Her account, published 25 years on, highlights how the firm and victims' families organised relief efforts amid overwhelming grief.

Gary Lutnick, 36 at the time of his death, was among the dead, while Howard survived as he had been out taking his son to his first day of kindergarten. Three days after the attacks, Edie became co-founder and later president of the Relief Fund, which Howard set up after pledging 25 per cent of Cantor's profits for five years plus a decade of healthcare for victims' families. The fund, run with volunteers working around the clock from donated office space, ensured all expenses were covered by Cantor itself so that 100 per cent of public donations reached families, a policy that continues today.
