An independent initiative group returning the name of the Ukrainian engineer Oleksandr Shargei to the global scientific and cultural context.

Oleksandr Shargei

A self-taught engineer from Poltava, known to the world as Yuri Kondratyuk, and one of the founding fathers of global cosmonautics.

  • A genius of global scale who, without formal education or scientific institutions, independently arrived at unique engineering ideas and stood alongside the leading theoreticians of the space age.

  • His story proves that even in the harshest conditions and complete isolation in provincial Poltava of the early 20th century, original ideas and world-class engineering calculations are capable of being born.

  • We want the world to know: Ukrainian engineering thought stood at the dawn of the space age. We are bringing Shargei back not for the sake of the past, but for our future—so that new generations can see this example of pure scientific freedom, resilience, and scale of thought.

The Genius of O. Shargei

O. Shargei belongs to the circle of pioneering researchers on a planetary scale, alongside Goddard in the U.S., Tsiolkovsky in Russia, and Oberth in Germany. It was they who laid the foundation of practical cosmonautics. Working completely autonomously, the self-taught engineer from Poltava proposed original engineering solutions and calculations that were decades ahead of their time. His 1929 book, "The Conquest of Interplanetary Spaces," is one of the most original in terms of mathematical purity of thought.
