Howard Gaberson, IEST Faculty Member
We were sorry to hear of the death of Howard Gaberson, IEST member and instructor on the topic of Pseudo Velocity Shock Analysis, on June 9, 2013. A shock and vibration specialist for more than 45 years, Dr. Gaberson published more than 110 papers and reports, with recent work on time frequency signal processing of machinery vibrations and the use of shock spectra for evaluation of explosion-induced equipment motion. In his early career, he taught at Lowell Technological Institute, Boston University, and the University of Hawaii. As senior technologist for the US Navy Civil Engineering Laboratory (NCEL) from 1968-1993 and the Naval Facilities Engineering Service Center from 1993-2000, his primary focus was dynamics research. At NCEL he also served as division director and project manager.

His friends at the Shock and Vibration Exchange (SAVE) and HI-TEST Laboratories remember:
Known to most as "Howie" and easily recognized by his signature vest … Howie was a great friend, teacher, and pioneer in the shock and vibration community. The Lifetime Achievement Award (in shock and vibration) was presented to Dr. Gaberson in November of 2007 at the 78th Shock and Vibration Symposium in recognition of a career dedicated to the improved understanding of shock and vibration processes. This award recognized his contributions and advancements spanning the width and breadth of shock and vibration research, particularly his work in evolving the shock spectrum pseudo-velocity as a central concept for assessment of equipment fragility.

In Memorial Dr. Willis Whitfield, IEST

In Memorial Dr. Willis Whitfield, IEST

Willis Whitfield

Everyone connected with IEST is saddened to learn of the passing of Willis Whitfield on November 12, 2012. In 2011, Dr. Whitfield was named a Fellow of IEST “For his pioneering breakthrough of the laminar flow cleanroom, which led to orders-of-magnitude improvements in manufacturing capabilities, cleanliness, and the protection of life from airborne hazards.” IEST also honors Dr. Whitfield each year by presenting the annual Willis J. Whitfield Award to worthy recipients for substantial contributions to the field of contamination control through published papers, studies, and reports.

From 1954 to 1984, Dr. Whitfield worked as a physicist at Sandia National Laboratories and was project leader for advanced development studies of microwave propagation measurements, contamination control, and cleanroom development. His idea to supply air to a cleanroom in a unidirectional flow instead of moving the air randomly about the room led to the construction of a model of the Whitfield cleanroom 1961. The idea was patented in 1964, and the introduction of contamination-free laboratories enabled the miniaturization of electronic and mechanical components, leading to our current cell phones, laptop computers, and the emerging field of nanotechnology.

Among his many honors, Dr. Whitfield was recognized by the American Society of Mechanical Engineers with the Holley Medal for the unique concept of the laminar flow cleanroom principle, and CleanRooms Magazine honored him as its first Hall of Fame inductee.

Robert Peck

IEST Fellow Robert (Bob) Peck died August 10, 2012, at age 90. Peck was respected as a pioneer in the concepts of cleanroom technology.

Peck was a member of IEST for 47 years and was heavily involved in the early development of the IEST Standards and Practices program. Peck received IEST’s Monroe Seligman Award (1984) and Robert L. Mielke Award (2006). He also was an early inductee of the Clean Rooms Hall of Fame, served as Executive Vice President of the American Association for Contamination Control, and was a member of ASME and ASHRAE.
