Question: John Stewart Kennedy was a member of the Jekyll Island Club alongside what Standard Oil co-founder?

Context paragraphs:
Cimarron-class oiler (1939): The "Cimarron" class oilers were an underway replenishment class of oil tankers which were first built in 1939 as "National Defense Tankers," United States Maritime Commission Type T3-S2-A1, designed "to conform to the approved characteristics for naval auxiliaries in speed, radius and structural strength", anticipating their militarization in the event of war.  "Tentative plans had been reached with the Standard Oil Company of New Jersey to build ten high-speed tankers with the government paying the cost of the larger engines needed for increased speed.  By the first week in December [1937], Standard Oil had solicited and received bids from a number of yards providing for the construction of a number of 16,300-ton (deadweight) capacity tankers.  Bids were requested for two versions: a single-screw design of 13 knots and a twin-screw design of 18 knots.  The price difference between the two would be used to establish the government's cost subsidy for greater speed.  Plans and specifications for both designs were prepared for Standard Oil by naval architect E. L. Stewart.  It seems certain that the design for the 18-knot tanker (Standard Oil Co. of New Jersey Design No. 652 NDF) evolved out of the bureau's (C&R) design for a fleet oiler."

James Ellsworth (industrialist): James William Ellsworth (October 13, 1849 – June 2, 1925) was an American industrialist and a Pennsylvania coal mine owner.  The coal town of Ellsworth, Pennsylvania is named after him.  He also served as president of the Caxton Club and the Jekyll Island Club.

Golden gimmick: The Golden Gimmick refers to a foreign tax credit deal enacted in November 1950 by the US Government under president Harry Truman between King Ibn Saud of Saudi Arabia and the Arabian-American Oil Company (ARAMCO), a consortium comprising Standard Oil of California (Chevron), Standard Oil of New Jersey (Exxon), Standard Oil of New York (Mobil) and Texaco.  King Ibn Saud was being influenced by Juan Pablo Pérez Alfonso of Venezuela who cut a similar 50/50 deal with New Jersey Standard Oil and Royal Dutch Shell.  This 50/50 deal accorded the American oil companies a tax break equivalent to 50% of their profits on oil sales, with the other 50% to be diverted to King Ibn Saud via the US Treasury.  The King agreed to this 50/50 splitting of Aramco's oil profits instead of nationalizing Aramco's oil facilities on Saudi soil.  Venezuela eventually led the effort in forming OPEC and Saudi Arabia gained full control of Aramco by 1980.

Standard Oil of Iowa: 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.

John Stewart Kennedy: 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.

Jekyll Island Club: 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.

Rockefeller Cottage: 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.

William Rockefeller: William Avery Rockefeller, Jr. (May 31, 1841 – June 24, 1922) was an American businessman and financier.  He was a co-founder of Standard Oil along with his older brother John Davison Rockefeller (1839–1937).  He was also a prominent member of the Rockefeller family.

The airport has 3 based aircraft, and around 74 aircraft operations a day.

Faith Chapel (Jekyll Island, Georgia): Faith Chapel is a historic chapel on Old Plantation Road in Jekyll Island, Georgia and was built in 1904.  It was used as a non-denominational chapel until 1942.  The state of Georgia purchased it along with Jekyll Island in 1947.  It is administered by the Jekyll Island State Park Authority and was opened to the public in 1970.  It has a wood "A" frame and a brick foundation.  The interior and exterior walls are shingled, with gargoyles that are replicas of the ones at Notre Dame Cathedral.  It has stained-glass windows.  One is "David's Window" which was made by Louis Comfort Tiffany.  Other stained glass windows are by Maitland Armstrong.  It was added to the National Register of Historic Places in 1971 and it is open to the public.
