Bridwell Botany Research Laboratory

2031 Constant Ave. Lawrence, KS 66047

Ronald L. McGregor, herbarium director 1954-88, oversaw a huge expansion of the botanical collections founded by Francis H. Snow, KU's first professor of natural history. To accommodate it, the collection was moved from Snow Hall to this 9,000-square-foot redbrick building in the West District, designed by George Beal, in 1966.

The research laboratory and herbarium are affiliated with the Biodiversity Institute.

The building is named for Joseph Sterling Bridwell (1885-1966), oil operator and cattle breeder from Wichita Falls, Texas, who funded KU research into developing better strains of grasses and legumes for cattle.

In 1985, the Bridwell Foundation endowed the construction of the east wing laboratory, designed by Kenneth O. van Achen. The herbarium was named in McGregor’s honor after his retirement. Bridwell also houses research space, a library, a slide collection, and more than 350,000 pressed specimens.
