5. Fast Food Moguls Ray Kroc
and Colonel Sanders
Milkshake machine salesman Ray Kroc was 51 when he stumbled upon a small chain of hamburger stands run by the MacDonald brothers and he pitched them on expanding the chain into a corporation.
in 1930, the then 40-year-old Sanders was operating a service station in Corbin, Kentucky, and
it was there that he began cooking for hungry
travelers who stopped in for gas. He didn’t have a restaurant yet, so patrons ate from his own dining table in the station’s humble living quarters.
It was then that he invented what’s called “home meal replacement” —
selling complete meals to busy, time-strapped families. He called it,
“Sunday Dinner, Seven Days a Week.”
