Chemistry and physics had been taught at KU since its earliest years, and pharmacy was added in 1885. Surging enrollments after World War II emphasized the mechanical and technological shortcomings of Bailey Chemical Laboratory and Blake Hall, science facilities designed before the turn of the 20th century. Planning began in 1949 for a new building that would house the departments of chemistry and physics and the School of Pharmacy. State Architect Charles Marshall designed a six-story, E-shaped building of native limestone to be built on the southwest slope of the hill.
Extensive planning was done to accommodate the wiring, plumbing and ventilation necessary for the various labs and research stations, and the massive structure, which included a science library, cost $3.4 million. At its dedication Nov. 5, 1954, it was named in honor of Deane W. Malott, the dynamic native Kansan and 1921 economics and journalism alumnus who was the eighth chancellor (1939-51). A huge addition designed by Peters, Williams & Kubota of Lawrence was dedicated April 10, 1981.
Malott houses the departments of chemistry and of physics and astronomy and its observatory; the departments of medicinal chemistry and pharmacology and toxicology in the School of Pharmacy; the Molecular Structures Group of laboratories in mass spectrometry, nuclear magnetic resonance, protein structures and other specialties; administrative offices; faculty and staff offices; classrooms; specialty laboratories and research facilities; the Animal Care Unit; and support and supply services.
Several departments will move to the new Integrated Science Building in the Central District when it opens in summer 2018. These include chemistry, medicinal chemistry, physics, and molecular biosciences.
A new School of Pharmacy building on west campus was completed in August 2010.
