Brooke Jackman had a photographic memory that earned her, at 23, an unofficial role as family historian. If her mother wanted to remember a decade-old conversation, she'd dial up Brooke, her youngest daughter, at her Murray Hill apartment. Usually Brooke recalled not only what was said, but what everyone was wearing at the time. In late August, she organized a family birthday outing: she, her parents and two siblings went to dinner in Greenwich Village, then to an Off-Broadway play.
She forever had her nose in a book, read everything from Sylvia Plath to ''Sex and the City''-style fluff, and stopped by the Borders bookstore almost daily on her way home from her new job as an assistant bond trader at Cantor Fitzgerald. She was, said her brother, Ross, literally the kind of person who would not hurt a fly. ''There were times I'd try to kill a bug, and she wouldn't let me.''
She grew up in Oyster Bay, N.Y., graduated from Columbia University in 2000 on the Dean's List, and gravitated to Wall Street, where her father and brother worked, after a year in publishing. But she was not completely fulfilled at Cantor Fitzgerald. ''She decided there were more important things in life than making money,'' said her brother. A master's in social work was her goal, and she was in the process of applying to Berkeley and Columbia to achieve it.
