Biography
Kopeć began his studies of the moulting of insects with Lymantria Dispar from specimens caught in the wild. His subsequent scientific activities helped determine the role of the insect brain in hormone production. He was the earliest researcher to understand the importance of the insect brain, as is demonstrated by his statement in a 1917 paper:
| “ | For the normal process of metamorphosis the presence of the brain, at least up to a certain moment, is indispensable... | ” |
Kopec's most significant contribution was his study of neurosecretory cells in the brains of insects which secrete a crucial growth hormone, prothoracicotropic hormone (PTTH), which regulates the process of metamorphosis (ecdysteroidogenesis). He observed that nervous tissue could behave like an endocrine gland. This discovery stimulated further scientific research leading to the establishment of the field of science known as neuroendocrinology. Kopec's work was cut short due to his arrest by the Gestapo in 1940 together with his daughter Maria and son Stanislaw in an action against the Polish underground university. He was imprisoned at the Pawiak Prison in Warsaw and executed by the Germans in 1941 at Palmiry, near Warsaw, together with his son as a reprisal against an action of the Polish underground army, as a part of the German AB-Aktion in Poland.
The University of Wrocław named its annual International Conference on Arthropods the Stefan Kopeć Memorial Conference in Kopec's honor.

Famous quotes containing the word biography:
“Had Dr. Johnson written his own life, in conformity with the opinion which he has given, that every man’s life may be best written by himself; had he employed in the preservation of his own history, that clearness of narration and elegance of language in which he has embalmed so many eminent persons, the world would probably have had the most perfect example of biography that was ever exhibited.”
—James Boswell (1740–95)
“As we approached the log house,... the projecting ends of the logs lapping over each other irregularly several feet at the corners gave it a very rich and picturesque look, far removed from the meanness of weather-boards. It was a very spacious, low building, about eighty feet long, with many large apartments ... a style of architecture not described by Vitruvius, I suspect, though possibly hinted at in the biography of Orpheus.”
—Henry David Thoreau (1817–1862)
“There never was a good biography of a good novelist. There couldn’t be. He is too many people, if he’s any good.”
—F. Scott Fitzgerald (1896–1940)
