5-39 Henry Morrison Flagler (1830-1913)

Side A: A founder of the Standard Oil Company, Henry Morrison Flagler spent his formative years in Bellevue and began his business career here in 1844, building his home near this site in 1858. He first became associated with John D. Rockefeller as a fellow grain merchant. The two later formed the Standard Oil Company in 1870 with capital partially furnished by members of the local Harkness family. Standard Oil became America’s largest and most powerful corporation in the late 1800s, and Flagler used his wealth to develop the state of Florida. His Florida East Coast Railroad, known as “the railroad over the sea,” extended from Jacksonville to Key West, Florida. The cities of Miami, Palm Beach, Fort Lauderdale, and St. Augustine grew with Flagler’s intensive development efforts.
