Arnold Arons was widely regarded as one of the leaders in physics and in physics education. He received his PhD in physical chemistry in 1943 from Harvard University. World War II brought Prof. Arons to the Woods Hole Oceanographic Institution, where he was a group leader in the Underwater Explosion Research Laboratory. He is well known for his studies here at WHOI of abyssal oceanic circulation and cloud physics and for experimental and theoretical work on phase distortion of acoustic pulses reflected from the seabed. From 1946 on, he taught at Stevens Institute of Technology, Amherst College, and University of Washington. In these years he revitalized the traditional physics of the time with his teaching techniques and numerous articles and books. His acomplishments included him in a TIME magazine story on education. Prof. Arons also served on many committees, including the NSF commission of college physics, as a trustee of the Woods Hole Oceanographic Institution and the American Institute of Physics. Prof. Arons passed on February 28, 2001 at his Seattle home.
