Henry Morrison Flagler (January 2, 1830 – May 20, 1913) was an American industrialist and a founder of Standard Oil, which was first based in Ohio. He was also a key figure in the development of the Atlantic coast of Florida and founder of the Florida East Coast Railway. He is also known as a founder of the cities of Miami and Palm Beach, Florida.

Early life and education

Flagler was born in Hopewell, New York. His father was Isaac Flagler, a Presbyterian minister and great-grandson of Zacharra Flegler, whose family had emigrated from the German Palatinate region to Holland in 1688. Zacharra worked in England for several years before moving to Dutchess County, New York, in 1710. His grandson Solomon changed the spelling of the surname to Flagler and passed it on to his 11 children. Flagler's mother was Elizabeth Caldwell Harkness Flagler, Isaac's third wife and a widow who had a stepson, Stephen V. Harkness, and a son, Daniel M. Harkness, from her marriage to deceased widower David Harkness of Milan, Ohio.

Flagler attended local schools through eighth grade. His half-brother Daniel had left Hopewell to live and work with his paternal uncle Lamon G. Harkness, who had a store in Republic, Ohio. He recruited Henry Flagler to join him, and the youth went to Ohio at age 14, where he started work in 1844 at a salary of US$5 per month plus room and board. By 1849, Flagler was promoted to the sales staff at a salary of $40 per month. He later joined Daniel in a grain business started with his uncle Lamon in Bellevue, Ohio, and made a small fortune distilling whiskey. He sold his stake in the business in 1858.

In 1862, Flagler and his wife's brother-in-law Barney Hamlin York (1833–1884) founded the Flagler and York Salt Company, a salt mining and production business in Saginaw, Michigan. He found that salt mining required more technical knowledge than he had and struggled in the industry during the Civil War. The company collapsed when the war undercut commercial demand for salt. Flagler returned to Bellevue having lost his initial $50,000 investment and an additional $50,000 he had borrowed from his father-in-law and Daniel. Flagler believed that he had learned a valuable lesson: invest in a business only after thorough investigation.

Business and Standard Oil

After the failure of his salt business in Saginaw, Flagler returned to Bellevue in 1866 and reentered the grain business as a commission merchant with the Harkness Grain Company. During this time he worked to pay back his stepbrother. Through this business, Flagler became acquainted with John D. Rockefeller, who worked as a commission agent with Hewitt and Tuttle for the Harkness Grain Company. By the mid-1860s, Cleveland had become the center of the oil refining industry in America and Rockefeller left the grain business to start his own oil refinery. Rockefeller worked in association with chemist and inventor Samuel Andrews.

Needing capital for his new venture, Rockefeller approached Flagler in 1867. Flagler's stepbrother Stephen V. Harkness invested $100,000 (equivalent to $ in ) on the condition that Flagler be made a partner. The Rockefeller, Andrews & Flagler partnership was formed with Flagler in control of Harkness' interest. The partnership eventually grew into the Standard Oil Corporation. It was Flagler's idea to use the rebate system to strengthen the firm's position against competitors and the transporting enterprises alike. Flagler was in a special position to make those deals due to his connections as a grain merchant. Equivalent to a 15% discount, they put Standard Oil in position to significantly undercut other oil refineries. By 1872, it led the American oil refining industry, producing . In 1877, Flagler and his family moved to New York City, which was becoming the center of commerce in the U.S.. In 1885, Standard Oil moved its corporate headquarters to New York City to the iconic 26 Broadway location.

By the end of the American Civil War, Cleveland was one of the five main refining centers in the U.S. (besides Pittsburgh, New York City, Philadelphia, and the region in northwestern Pennsylvania where most of the oil originated).
