answer: William Rockefeller
context: Title: Rockefeller Cottage
  Passage: The Rockefeller Cottage is a house on Jekyll Island, Georgia.  It is also called "Indian Mound" and is next to the Jekyll Island Club.  The house was built by Gordon McKay in 1892.  McKay died in 1903 and the house was bought by William Rockefeller in 1905, who used it as a winter home.  It was evacuated in 1942, along with the rest of the island.  The house remained in the Rockefeller family until 1947, when the Jekyll Island Authority bought the property.  It was open as a museum from 1950 until 1968, when it was closed for badly needed repairs.  It is now a public museum.  It was added to the National Register of Historic Places in 1971.

  Title: Jekyll Island Club
  Passage: The Jekyll Island Club was a private club on Jekyll Island, on Georgia's Atlantic coast.  It was founded in 1886 when members of an incorporated hunting and recreational club purchased the island for $125,000 (about $3.1 million in 2017) from John Eugene du Bignon.  The original design of the Jekyll Island Clubhouse, with its signature turret, was completed in January 1888.  The club thrived through the early 20th century; its members came from many of the world's wealthiest families, most notably the Morgans, Rockefellers, and Vanderbilts.  The club closed at the end of the 1942 season due to complications from World War II.  In 1947, after five years of funding a staff to keep up the lawn and cottages, the island was purchased from the club's remaining members for $675,000 (about 7.4 million in 2017) during condemnation proceedings by the state of Georgia.
  Title: John Stewart Kennedy
  Passage: John Stewart Kennedy (January 4, 1830 – October 30, 1909) was a Scottish-born American businessman, financier and philanthropist.  He was a member of the Jekyll Island Club (also known as The Millionaires' Club) on Jekyll Island, Georgia along with J.P. Morgan and William Rockefeller among others.
  Title: Standard Oil of Iowa
  Passage: Standard Oil Company of Iowa was created in 1885 as a subsidiary of the Standard Oil Trust to handle marketing along the Pacific Coast states of Idaho, Oregon, Washington, California, and Arizona.  Though named for the midwestern state, it never included Iowa as one of its primary marketing areas.  A prior company named Standard Oil of California had been formed in 1877, and was not associated with the Standard Oil Trust.  In 1906, Standard Oil of Iowa was dissolved and its assets handed over to a new Standard Oil of California, later Chevron Oil Company, and now the Chevron Corporation.  Standard Oil Company of Iowa is thus the original company that is now Chevron.
