Completed in 1981, Lopata Hall was named for Stanley Lopata, and is the main entrance to the engineering complex, serving as a physical link between Sever, Cupples II, and Urbauer Halls. A unique feature of the bulding is the four-story Lopata Gallery. During the first few years of the gallery's existence, there were plants hanging from the ceiling. However, these plants made the air so humid that it would occasionally rain on the people below, so the plants were removed.
Stanley Lopata was a 1935 Washington University College of Arts & Sciences graduate. Founders of Carboline Corporation, Mr. and Mrs. Lopata grew the basement chemical laboratory into a $46 million business. Together, they have been longtime friends of the University, and especially the School of Engineering. Other memorials to them on campus are Lopata Courtyard in Simon Hall, the Lopata Classic, a men's basketball tournament held every fall, and Lopata Plaza. The Village also bears their name on the Lucy and Stanley Lopata House.
