Douglas K. Lilly was a renowned meteorologist who had a significant impact on the field of atmospheric sciences. Although Lilly completed his undergraduate work in physics at Stanford University on a Navy ROTC scholarship, he always envisioned going into meteorology.

Ed Martell was a distinguished nuclear scientist with a focus on atmospheric chemistry, radioactive material, and nuclear science in general. His academic journey began at West Point, where he graduated in the class of 1942. Following his graduation, Martell served as an officer in the Corps of Engineers for eight years, participating in combat in the Pacific during the Second World War. After the war, Martell had the opportunity to further his studies at the University of Chicago as a lieutenant colonel. It was here that he earned his Ph.D. in nuclear chemistry and radiochemistry in 1950.

William Kellogg begins by describing his first acquaintance with the NCAR concept, and his belief in the benefits of team research or big science. He notes the first retreat meeting at Keystone and offers examples of problems that required an interdisciplinary approach. He mentions chairing a group for a larger study called the "Study of Critical Environmental Problems" ("SCEP" study for short), which wrote on human influences on climate, and discusses the challenges of getting scientists to work together, relating an anecdote about having to fire a dynamic meteorologist.
