Stefan Gelineo, Croat by birth, born in Stari Grad on the island of Hvar (1898-1971), studied in Leipzig and Vienna. He was the professor of physiology at the University of Belgrade (capital of Serbia and former Yugoslavia). He is internationally known by his contributions to the study of hypothermia, i.e. the study of vital functions under low temperatures.
Stjepan Mlakic (1844-?) Bosnian Croat born in Fojnica, a missionary in Africa among the tribes of Shiluks and Nuers in Sudan, like his colleague Kohnen. Very educated, besides his native Croatian he spoke German, Italian, English and Arabian, to which he added the language of Nilot tribe of Nuers. His letters to his brother (also a priest) in Bosnia witness about his very close contacts with Africans. It is worth to note his discovery that in Egypt, near the town…
Bernardo Kohnen (1876-1937), German by birth, born near Hannover, moved as a young boy with his parents to Bosnia, where he attended the famous Jesuit gymnasium in Travnik. He devoted about 30 years of his life to the evangelization and study of life of Shiluks (southern Sudan), at that time one of the most isolated tribes in Africa, and other Nilot tribes (Denka, Nuer, etc). “Father Shiluk”, as he was called by the Shiluks themselves, wrote first dictionaries, grammars, and…
Fran Bosnjakovic (or Franjo Bosnjakovic, 1902-1993), born in Zagreb, was one of world’s leading experts in technical thermodynamics. Educated in Zagreb, where his scientific career started in 1926, he moved to Dresden, Germany, in 1928. In 1931 he became university teacher at Dresden High Mechanical Engineering School. After a short stay in Belgrade, he moved back to the University of Zagreb in 1936. He was a collaborator of Croatian Encyclopaedia. After 1945, during the Yugoslav communist regime, he was degraded…
Danilo Blanusa (1903-1987), Croatian mathematician, professor at the University of Zagreb, was born in Osijek. He discovered a mistake in relations for absolute heat Q and temperature T in relativistic phenomenological thermodynamics, published by Max Planck in Annalen der Physik in 1908: Q = Q0 a, T = T0 a , where Q0 and T0 are the corresponding classical values, and a = (1-v2/c2)1/2. Blanusa proved that the correct relations should be Q = Q0 / a, T = T0…
William Feller (Vilim, Willy, Willi, 1906-1970) is a well known name among mathematicians dealing with probability theory. He was born and educated in Zagreb as Vilim Feller, where he studied mathematics for two years (completing 4 semesters out of 8), and then in 1926 continued his studies at the University of Göttingen. By the end of the same year, at the age of 20, he defended his doctoral degree in mathematics. Göttingen at that time the strongest mathematical center in…
The Savannah nuclear ship, the first nuclear-powered merchant ship, was built to the plans of Erazmo Tićac. Born in Žurkovo in 1904, Erazmo went to schools in Žurkovo, Kostrena and Bakar, and made a career as a shipbuilding engineer in the USA. After the president Dwight Eisenhower announced his decision to build an experimental nuclear-powered merchant ship in 1955. Erazmo Tićac, planner of the Savannah nuclear ship. Source of the photo. The planning was entrusted to the firm The Sharp…
George M. Skurla (1921-2001), after completing his college training, he joined the Aircraft Engineering Corporation as an apprentice engineer. In 1965, he became director of operations for Grumman at the National Aeronautics and Space Administration’s (NASA) Kennedy Space Center (KSC). In that position, he brought together the 1,600-man Grumman team responsible for the final assembly, test and pre-launch checkout for the Apollo lunar module vehicle. Skurla led the team that built the historic Apollo 11 lunar landing module. The lunar…

Jacob Jake Matijevic (1947-2012), of Croatian origin, PhD in Mathematics from the University of Chicago, was NASA engineer and a father of Curiosty rover which successfully landed on the planet Mars in 2012. NASA named several landmarks, including “Matijevic Hill” and “Jake Matijevic” rock, for him on the planet Mars. Dr. Jacob Jake Matijevic died a few weeks after his rover landed on Mars.
