From the Lawrence Daily Journal-World for July 19, 1989:

A retired Kansas University botany professor and his wife had committed $586,000 to establish an endowed fund to benefit KU’s herbarium. The gift from Ronald and Dorothy McGregor would supplement maintenance and operating expenses for the facility. “Collections and museums are always hard put financially and this is one way of ensuring the support,” said McGregor, 70, who had retired the previous December. “This is what I’ve done for all of my life and it’s something I can continue supporting. It’s been the biggest thrill to work at KU all these years and to live in Lawrence.” The herbarium, home to more than 350,000 plant specimens, was located on Constant Ave. on KU’s west campus. Under McGregor’s supervision, the herbarium had grown from a small collection to the largest one in the central and northern plains region.
