Paul Joseph Kaesberg

Paul Joseph Kaesberg (September 26, 1923 – December 24, 2010) was a German-born American biochemist and virologist[1] who was known worldwide for his extensive research regarding small viruses.

In 1926,[3] his parents Gertrude and Peter Kaesberg, moved to the United States of America, and chose to settle in the city of West Bend, Wisconsin.

[6] In 1955, Robert Rice and Kaesberg researched why the tobacco mosaic virus breaks apart after preservation via freeze-drying.

[3] In 1958, Kaesberg and colleagues discovered a mosaic virus found in alfalfa creates three macromolecules after infecting a plant.

These particles looked nothing like the known spherical species of the alfalfa mosaic virus, so they discovered a new isolate in their work.

An increase in pH also causes the virus’ intrinsic viscosity and diffusion coefficient to decrease.

[11] In 1954, Kaesberg and Paul Schmidt utilized small-angle X-ray scattering to measure the size of the yellow turnip mosaic virus and its associated protein.

[12] In 1963, Margaret Wright and Paul Kaesberg used x-ray scattering to learn more about the inside of the bromegrass mosaic virus.

They saw that the internal region was almost wholly empty and that the RNA and protein within the virus had almost equal electron densities.
