Professor Dr. Hans Rudolf Pruppacher was a towering figure in the international cloud physics community.

He was a researcher, teacher, and mentor, and had immense impact on both experimental and theoretical
developments in the field of atmospheric science. Hard working and demanding at the workplace,
Hans was very kind to his students in personal relations.

The publication of the book “Microphysics of Clouds and Precipitation”, co-authored with James D. Klett in 1978,
is still an important contribution to the cloud physics field.
His research is gaining even more importance as recent climate studies have underlined the fundamental
uncertainties resulting from clouds.

Hans Pruppacher passed away on 11 oct 2020 after a short and brave fight against a brain tumour
and is survived by his wife Monica and his son Lucas.
Due to current regulations, the funeral ceremonies are restricted to his close family.
