What the Edison Family Story Teaches Us

A Loyalist-exiled Canadian father. A homeschooling schoolteacher mother. Two marriages — one ending in his wife's death at 29; the second a 45-year marriage to the daughter of another inventor. Six children — one of whom became Governor of New Jersey. A lab that became General Electric.

For every family — large or small, famous or otherwise — the Edison story carries the same lesson. Sometimes one child of an inventor goes into politics, not invention. Charles Edison's political career is on the family tree alongside 1,093 patents. Write down which children went their own way. The diverged paths are themselves family choices.
