Francisco began working on the sly as a teenager in order to learn all he could about business. While still a student at Patrick Henry University, he began working at a copper foundry, and investing in the stock market. By the time he was 20 he had made enough to purchase the foundary. He began working for d'Anconia Copper as assistant superintendent of a mine in Montana, but was quickly promoted to head of the New York office. He took over d'Anconia Copper at age 23, after the death of his father.
When he was 26, Francisco secretly joined the Strikers and began to slowly destroy the D'Anconia empire so the Looters could not get it. He adopted the persona of a worthless playboy, by which he is known to the world, as an effective cover.
His full name is Francisco Domingo Carlos Andres Sebastian d'Anconia.

According to [Adam Reed] ( [link]), d'Anconia is the only Hero-class character who is recognizably Jewish (of course not in the religious, but in the historical sense, like Ayn Rand herself). See Who Is Francisco D'Anconia?
