Benjamin Y. H. Liu was born in Shanghai, China in
1934. He grew up in war-time China on the
mainland, went to college in Taiwan, received his
B.S.M.E. degree from the University of Nebraska
in 1956, and his Ph.D. from the University of
Minnesota in 1960. Dr. Liu began his academic
career at the University of Minnesota as an
Assistant Professor. He was elected to the
National Academy of Engineering in 1987. He is a
co-founder of the AAAR and of the society's
journal, Aerosol Science and Technology, and
helped establish the International Aerosol
Research Assembly. He received the Fuchs Memorial
Award in 1994 and retired as Regents' Professor
from the University of Minnesota in 2002, where
he also served as the director of the Particle
Technology Laboratory from 1973 to
1997. Following his retirement from the
University of Minnesota, Dr. Liu became the CEO
and President of MSP Corporation, a company he
co-founded with Prof. V. A. Marple.

• Prof. Lius contributions to aerosol science
  include
• theory on aerosol sampling and transport
• aerosol charging and precipitation
• inertial impaction
• filtration
• atmospheric aerosol research and
• contaminant particle deposition on wafers.
• He and his students have pioneered the
  development of many instruments and experimental
  techniques including
• the vibrating orifice generator and
• the electrostatic classifier
• that have provided accurate size standards needed
  by the aerosol community to perform modern
  aerosol experiments with high accuracy and
  precision.

2004 Recipients of the Benjamin Y. H. Liu Award
Douglas R. Worsnop, Vice President, and John T.
Jayne, Principal Scientist, Aerodyne Research,
Inc.
Their mass spectrometer system (AMS) with
molecular beam, aerosol focusing, and thermal
vaporization have created a paradigm shift in
online, size-resolved atmospheric aerosol
composition. The supporting letters all
highlighted their dedication to supporting the
many AMS users to do the best science possible
with the instrument.
