Guenter Ahlers received his BA degree in Chemistry from the University of California at Riverside in 1959. At Riverside, he specialized and wrote a Thesis in Theoretical Chemistry. He received his Ph.D. in Physical Chemistry from the University of California at Berkely in 1963. His Ph.D.-thesis research involved an experimental study of the thermodynamic properties of solid hydrogen under pressures up to 10 kbar. While at Berkeley, he also initiated calorimetric investigations of solid $^4$He under pressure. He became a Member of Technical Staff at Bell Laboratories in 1963, and remained in that position until 1979. At Bell, he continued his studies of the equation of state of solid helium, but in addition carried out calorimetric studies of metals. In 1967, he began his work in the field of critical phenomena, an area of interest to him up to the present time. He studied the superfluid transition in liquid $^4$He, as well as phase transitions in ferromagnets and antiferromagnets. In 1971, he began working as well on nonlinear nonequilibrium systems. In 1979, Ahlers accepted a position as Professor of Physics at the University of California at Santa Barbara. At UCSB, he continues to pursue his interests in critical phenomena near the superfluid transition of $^4$He, and in nonequilibrium phenomena with an emphasis on the problem of pattern formation, spatio-temporal chaos, and the formation of localized structures or pulses.
