Bernadine D. Tschudy

Palynologist Bernadine D. Tschudy (U.S. Geological Survey, retired) died 21 November 1998 in Longmont, Colorado. She was 91. Bernadine was the wife of Dr. Robert H. Tschudy. who preceded her in death in October 1986. In the late 1940's Bernadine and Robert Tschudy joined the Creole Oil Company in Caracas, Venezuela, where they began pioneering work in the identification of fossil pollen and spores and the application of palynology to petroleum exploration. They spent five years in Venezuela before moving to Boulder. Colorado. There they continued doing consulting work for major oil companies until 1961 when they both joined the U.S. Geological Survey. They continued their careers at USGS in emeritus positions long after retirement.

Bernadine specialized in Cretaceous palynologv and was particularly interested in the taxonomy of the genus Aquilapollenites. In recent years she preferred to spend her winters in the desert community of Borrego Springs, California. and her summers in Longmont and Boulder. Colorado, Until quite recently she was extraordinarlily active, walking several miles each day.

She is fondly remembered by close friends and former colleagues throughout the U.S.
