MacGregor Park is significant for its association with two notable Houstonians: Henry F. MacGregor, a businessman and philanthropist who did much to shape Houston’s growth and development in the first quarter of the 20th century, and Olympic champion Zina Garrison, who became a world champion tennis player through John Wilkerson’s MacGregor Park junior tennis program in the 1970s. The original 1936–37 plan for the parkway between the North and South MacGregor Way was created by the renowned landscape architecture firm Hare & Hare of Kansas City, Missouri, which carried out much of Houston’s park development in the second quarter of the century. MacGregor Park provides a link to Hermann Park along Brays Bayou and is an important site within the City of Houston Park System.
