Pan American Round Table Houston (PART Houston) was established in 1940 by Hallie Barlow Olcott. Early members included Maude Cashin, Ima Hogg, Mary Fuller and 16 others. Over these 76 years, the Houston membership has included a wide spectrum of accomplished women who are interested in furthering the knowledge of the cultures, customs, and history of the Americas. Programs include speakers from business, government, academia, science and the arts. Education continues to be a mission for the Houston Table, which sponsors and provides support through college scholarships to state and local students. Since 1995, the Houston Table has awarded approximately $225,000 in scholarships. In 2016, the Houston table awarded 20 scholarships to worthy Houston scholars.
