According to a definition, a "self-made man" or "self-made
woman" is a person who was born poor or otherwise disadvantaged,
but who achieved great economic or moral success thanks to their
own hard work and ingenuity rather than to any inherited fortune,
family connections, or other privilege. The biography of David
Sarnoff (1891-1971) – american communicator and businessman,
one of the founders of radio and television broadcasting in the United
States – clearly illustrates the idea of a "self-made man".
