Margaret Fagenson, the wife of a millionaire Wall Street legend, jumped to her death from the 14th floor terrace of her luxury New York City apartment.

The 68-year-old was reportedly suffering from depression, and died at the scene after landing on a sidewalk next to her building, the Henderson House.

She was identified by sources at the scene around 10:50am on Thursday, reported the New York Daily News.

One witness who saw Fagenson leap was too far away to help, and she did not leave a note.

Robert Fagenson, her husband, is the CEO of a boutique investment bank in New York, Fagenson & Co. He reportedly appeared devastated as he stood next to his wife's body, holding their two dogs.

A shocked friend said to the New York Post: 'She is the last person who would do such a thing'.

Fagenson was a prominent animal rescue donor, and the couple supported for years groups such as the American Society for the Prevention of Cruelty to Animals and the Humane Society.
