Tribute to James M. Kelly
It is with profound sadness that we announce the death of Professor Emeritus James Marshall Kelly in Berkeley on September 23, 2025, at the age of 90. Professor Kelly was probably the most influential figure in the development, design, and implementation of seismic protection technologies and is widely regarded as the Father of Seismic Isolation. Brilliant, wise, and generous, he earned the admiration of students, colleagues, and collaborators around the world.
