Joseph Rotblat

Sir Joseph Rotblat KCMG CBE FRS (4 November 1908 – 31 August 2005) was a Polish physicist, a self-described “Pole with a British passport”.[2] Rotblat worked on Tube Alloys and the Manhattan Project during World War II, but left the Los Alamos Laboratory after the war with Germany ended. His work on nuclear fallout was a major contribution toward the ratification of the 1963 Partial Nuclear Test Ban Treaty. A signatory of the 1955 Russell–Einstein Manifesto, he was secretary-general of the Pugwash Conferences on Science and World Affairs from their founding until 1973 and shared, with the Pugwash Conferences, the 1995 Nobel Peace Prize “for efforts to diminish the part played by nuclear arms in international affairs and, in the longer run, to eliminate such arms.”

Yuri Kondratyuk

Yuri Vasilievich Kondratyuk (real name Aleksandr Ignatyevich Shargei, Russian: Алекса́ндр Игна́тьевич Шарге́й, Ukrainian: Олександр Гнатович Шаргей) (21 June 1897 – February 1942) was a Soviet engineer and mathematician. He was a pioneer of astronautics and spaceflight, a theoretician and a visionary who, in the early 20th century, developed the first known lunar orbit rendezvous (LOR), a key concept for landing and return spaceflight from Earth to the Moon. The LOR was later used for the plotting of the first actual human spaceflight to the Moon. Many other aspects of spaceflight and space exploration are covered in his works.

Kondratyuk made his scientific discoveries in circumstances of war, repetitious persecutions from authorities and serious illnesses.

“Yuriy Kondratyuk” is a stolen identity under which the author was hiding after the Russian revolution and became known to the scientific community.

Évariste Galois

Évariste Galois (/ɡælˈwɑː/; French: [evaʁist ɡalwa]; 25 October 1811 – 31 May 1832) was a French mathematician and political activist. While still in his teens, he was able to determine a necessary and sufficient condition for a polynomial to be solvable by radicals, thereby solving a problem standing for 350 years. His work laid the foundations for Galois theory and group theory, two major branches of abstract algebra, and the subfield of Galois connections. He died at age 20 from wounds suffered in a duel.
