Katherine Esau
Katherine Esau (3 April 1898 – 4 June 1997) was a German-American botanist who received the National Medal of Science for her work on plant anatomy. Personal life and education Esau was born on 3 April 1898 in Yekaterinoslav, Russian Empire (''now Dnipro, Ukraine'') to a family of Mennonites of German descent, so-called "Russian Mennonites". She began studying agriculture in Moscow, but after a year her family was prompted by the Bolshevik Revolution to move to Germany where she completed her studies at the Agricultural College of Berlin. This had provided training in plant breeding. The Esau family moved to California in 1922, where Esau worked for the Spreckels Sugar Company on sugar beet resistance to curly top virus. From 1927 Esau was employed as a graduate assistant in the Botany Division and resumed her education at the University of California, Davis, through registering for a PhD degree at University of California Berkeley in 1928 (Davis did not have a graduate schoo ...

Dnipro
Dnipro, previously called Dnipropetrovsk from 1926 until May 2016, is Ukraine's fourth-largest city, with about one million inhabitants.

The population of Dnipro is Archeological evidence suggests the site of the present city was settled by Cossack communities from at least 1524. The town, named Yekaterinoslav (''the glory of Catherine''), was established by decree of the Emperor of all the Russias, Russian Empress Catherine the Great in 1787 as the administrative center of Novorossiya Governorate, Novorossiya.

Thomas Harper Goodspeed
Thomas Harper Goodspeed (17 May 1887 Hartford, Connecticut - 17 May 1966 Calistoga California) was a botanist specializing in the genetics of species ''Nicotiana''. He was the director of the University of California Botanical Garden from 1919 to 1957. Under the direction of Goodspeed and University of California landscape architect, John William Gregg, the garden was moved from its location on the central campus to its current site in Strawberry Canyon in the hills above the campus. Among his doctoral advisees was the plant anatomist Katherine Esau. As director of the UCBG, Goodspeed led several plant hunting expeditions to the Andes of Colombia, Peru, Chile, Argentina, and Uruguay. He obtained a substantial collection of ''Nicotiana'' during these expeditions, which were then assembled at the Botanical Garden for further study. His study lead to increased understanding of the origins and diversity of tobacco species. The collection was later used to reintroduce wild disease ...

Electron Microscope
An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination. As the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, electron microscopes have a higher resolving power than light microscopes and can reveal the structure of smaller objects. A scanning transmission electron microscope has achieved better than 50 pm resolution in annular dark-field imaging mode and magnifications of up to about 10,000,000× whereas most light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000×. Electron microscopes use shaped magnetic fields to form electron optical lens systems that are analogous to the glass lenses of an optical light microscope. Electron microscopes are used to investigate the ultrastructure of a wide range of biological and inorganic specimens including microorganisms, cells, large molecules, biopsy samples, ...
