In Memoriam

Dr. Graham Morrison

Dr. Graham Morrison joined NBS in 1980, as a research chemist who specialized in identifying alternatives to ozone-damaging refrigerants.  He graduated from Lehigh University and received his doctorate in chemistry from Cornell University.

At a time before the potential damaging effects of refrigerants was clearly understood, Morrison's early research focused on identifying the measurements that should be made to quickly and efficiently study the thermophysical properties of refrigerants.  His research was instrumental in developing NIST's program on alternative refrigerants.

In 1985 Morrison began publishing papers on the properties of refrigerant mixtures; one of the most important was the 1986 NBS Technical Note 1226, "applications of a Hard Sphere Equation of State to Refrigerants and Refrigerant Mixtures," co-authored with Dr. Mark McLinden. The computer program REFPROP that he coauthored has become a standard for scientists and engineers that are designing new, environmentally friendly refrigerators, heat pumps, and air conditioners. 

Among the awards Morrison received as the result of his work were the prestigious NIST Applied Research Award (joint with Mark McLinden), the Department of Commerce Silver Medal, and the Measurement Service Award.  

Outside the lab, Graham was a volunteer researcher, radio program developer, and reader for the programs that assisted visually and physically handicapped.


Dr. Robert D. Goodwin
(1915 - 1994) 

Dr. Robert D. (Bob) Goodwin joined the Cryogenic Engineering Laboratory of NBS in Boulder in 1955, after receiving his Ph.D. in chemistry from the Johns Hopkins University.  His first project was the development of a thermostating system for quartz-crystal time standards.  He quickly moved on to a comprehensive and large project on the thermodynamic and transport properties of parahydrogen.  This work was in support of the space program of the early sixties.  Parahydrogen was used as a propellant for the rockets and as a monopropellant in nuclear rocket-propulsion systems.  This work earned the Department of Commerce Gold Medal.  He was responsible for much of the early design of the low-temperature thermophysical-property instrumentation developed in the Division.  Throughout his career in fluid-properties measurement he maintained a keen interest in equations of state and eventually devised the equation that bears his name.  He retired in 1985 after 30 years of Federal service. 

He was an active ski mountaineer, and served in the Rocky Mountain rescue Group.  Bob always took an interest in the careers of younger staff members and postdoctoral associates.  He was always there with good advice and encouragement.



Dr. Lloyd Weber (1935 - 1999)

Dr. Lloyd Weber earned a PhD. degree in Physical chemistry from Rice University in 1960.  He then joined the Cryogenics Engineering Laboratory of the National Bureau of Standards (now the National Institute of Standards and Technology) in Boulder, Colorado.  At NBS/NIST, Dr. Weber first measured the properties of liquid hydrogen, oxygen, and nitrogen.  His results were used by NASA to help design liquid-fueled rockets.  For this work, Dr. Weber and 5 colleagues shared the Department of Commerce's Gold Medal in 1966.  

Dr. Weber also made extensive measurements of the properties of newly synthesized liquids that were environmentally acceptable candidates to replace the refrigerants that were considered to be ozone depleting .  His results were used by industry and by the US Navy to optimize the design of a wide range of air conditioning and refrigeration systems.  In addition to obtaining engineering data, Dr. Weber improved the accuracy and efficiency of the apparatuses used to measure vapor pressure, the equation of state, heat capacity, and dielectric constants of liquids and gases.


Dwain E Diller (1927-2014) 

Dwain E Diller joined NBS in 1959 after working at B.F. Goodrich for five years. He received his B.S. in Physics (magna cum laude) from Baldwin-Wallace University in 1950, and his M.S. in physics from Case Western Reserve University in 1953. He was a member of the Cryogenics Division of NBS, and later the Properties of Fluids Group. Indeed, Mr. Diller served as Section Chief of this Group.

Dwain was a pioneer in the measurement of fluid viscosity by use of the torsional crystal method. His measurements on the viscosity para-hydrogen, making use of this method, have had lasting impact in the aeronautics and aerospace industries.This work was part of a team effort that succeeded in developing a complete picture of the properties of hydrogen, for which the five member team was awarded the Department of Commerce Gold Medal in 1966.

Later in his career, Mr. Diller's measurement activities turned toward mixtures important for natural gas, liquefied natural gas, and later, alternative refrigerants. His work resulted in publication of over 50 papers, and presentations worldwide.He remained associated with NIST as a guest researcher until 2010, serving as a sought after reviewer of papers and a trusted adviser to junior staff. 

Outside NIST, Mr. Diller was a volunteer at the Nomad Theater, the Boulder Public Library and Boulder Community Hospital. He is survived by three children, seven grand-children and eight great-grand children.
