Robert D. Liska passed away on January 24, 2021. He died peacefully at home in the presence of his much-loved wife of 64 years. Born in 1931, Bob earned his MSc in Geology at San Diego State University. In 1963 Bob joined Texaco in Long Beach, California as a geologist. Two years later he joined Texaco International in Colombia, and in 1973 moved to Trinidad. Bob had a long association with Micropaleontology Press, and published several papers in Micropaleontology and in the Journal of Foraminiferal Research in the 1980’s and 1990’s. Bob leaves behind the legacy of his lifelong passion for micropaleontology and stratigraphy: his extensive and unique microfossil collection which will be housed at University College London, and his equipment which was donated to Texas A&M.
