What the Tesla Family Story Teaches Us

A Serbian Orthodox priest father. A mechanically inventive mother whose father was also a priest. An elder brother (Dane) lost at 12 in a horse accident. Three sisters. A lifelong unmarried life in NYC hotels. A career that gave the world AC electricity but ended in obscurity and poverty.

For every family — large or small, famous or otherwise — the Tesla story carries the same lesson. The mother's quiet skills often run in the children. Đuka's inventive temperament is on the Tesla family record alongside every patent. Write down which parent passed down which skill. The early model often comes from the parent who never claimed credit.
