Dr Anil Singh passed away in 2025.

Anil Singh (1939–2025)

It is with great sadness and a sense of personal loss that we inform you that our close friend and colleague Dr. Anil Singh passed away recently in his hometown of Bangalore, India.

Anil made wide-ranging and major contributions in the fields of high-pressure solid state and mineral physics, especially on lattice strains and X-ray diffraction under nonhydrostatic stress, crystal structure analysis, electronic and structural phase transitions, volume compression, elastic properties and equation of state at high pressure. He was adept in both theory and experiments and founded the high-pressure laboratory using mostly his own designs in the National Aerospace Laboratories, Bangalore, India, of which he was the Head of the Materials Science Division. In 1991, Anil served as the Conference Chairman and editor of the Conference Proceedings of the XIII AIRAPT International Conference in Bangalore. He was a member of the Executive Committee of AIRAPT, Commission on Crystallography at Controlled Pressure and Temperature, International Union of Crystallography and many other National and International committees/organizations.

Anil’s transition from a crystallographer to high pressure research began with his tenure as a post-doc in the early 1970s in George Kennedy’s group in the Institute of Geophysics and Planetary Physics at UCLA. There he left a lasting impression as a brilliant and friendly young scientist on both Kennedy and his young colleagues that included one of us (JG). Later he was a Visiting Scientist at the CESMEC (Center for Study of Matter under Extreme Conditions, Florida International University, where he collaborated with one of us (PL) and others), the Geophysical Laboratory, Washington, the University of Arizona and the Deutsches Elektronen Synchrotron. Anil continued collaboration with two of us (PL, SS) on the application of lattice strain theory.

Anil was an engaging, easy going and humorous person, a good tennis and badminton player, and an ideal family man. He is survived by his wife, Pratibha; daughters, Archana and Vandana; sons-in-law and grandchildren.
We will miss him dearly.
