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 1980â€™s and 1990â€™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.
