In 1899, nine-year-old Thomas Gilcrease received 160 acres; 18 years later, it had 32 producing oil wells, and his wealth later helped build Tulsa's Gilcrease Museum

• ​Financial troubles forced Gilcrease to give up control of his collection and museum to the City of Tulsa in 1955.
• Thomas Gilcrease was just nine-year-old when he became eligible for a 160-acre land allotment in Oklahoma through his Creek tribal membership in 1899.
• The land, near present-day Glenpool, later became part of the Glenn Pool oilfield, where oil was discovered in 1905.
