Thomas Edison
He married Mary Stilwell in 1871. He had three children in that marriage: Marion Estelle Edison (also called Dot), Thomas Alva Edison, Jr. (also called Dash) and William Leslie Edison. Mary Stilwell died in 1884. Thomas Edison bought some land in Florida and built a house. When he was thirty-nine, Edison married his second wife, Mina Miller, who was 19. He had 3 children in that marriage: Madeleine Edison, Charles Edison (who took over the company when his father died and was later elected Governor of New Jersey), and Theodore Miller Edison. When he got older, he would throw dinner parties for fellow inventors. Since he was older, he had impaired hearing, so his wife would tap out all the conversations at the dinner table in Morse code in to his hand.
