William Christian Krumbein (1902-1979) was a notable geologist, after whom the Krumbein Medal of the International Association for Mathematical Geology (IAMG) was named. Mathematical Geology is an international geoscientific Journal, edited by the IAMG ( International Association of Mathematical Geology This medal was established at the 25th International Geological Congress in Sydney, in 1976. The International Union of Geological Sciences (IUGS is an international Non-governmental organization devoted to international cooperation in the field of Geology Krumbein was a founding officer of the IAMG.
Krumbein was born at Beaver Falls, Pennsylvania, USA, in January, 1902, and died on August 18, 1979. The Commonwealth of Pennsylvania ( often colloquially referred to as PA (its abbreviation by natives and Northeasterners is a state located in the Northeastern The United States of America —commonly referred to as the At his memorial service, it was said of Krumbein "that by constitutionally rejecting conventional wisdom, he continually pursued innovative methods, whereby the natural phenomena of geology could be expressed with mathematical rigor. "
The legacy left by Krumbein includes his 'Krumbein Scale', a system of measuring 'roundness' or 'sphericity' of particles and the Krumbein phi (φ) scale, a logarithmic scale used for evaluating particle size that is a modification to the older Wentworth scale. Sphericity is a measure of how spherical (round an object is As such it is a specific example of a Compactness measure of a shape.
