During the early period of rocket development several pioneers originating from the former Austro-Hungarian empire contributed their ideas to the new field of rocketry. The most well known - regarded as the "father of rocketry" in Western Europe - is Hermann Oberth. The others were Max Valier, Franz von Hoefft, Guido von Pirquet, Hermann Potocnik, Friedrich Schmiedl, Franz Ulinski, Eugen Saenger and others. Franz Ulinski (1890-1974) was born 1890 in Blosdorf, Moravia (now Mljadejow, Czech Republic). After attending schools in Wels, Upper Austria, he started a career in the Austro-Hungarian Army in 1910. During his service he worked beginning 1917 at an airplane engine plant in Fischamend and in 1919/20 at the "Fliegerarsenal" (aircraft arsenal) in Vienna. End of 1920 the army of the remaining republic of Austria had to severely reduce its forces and Ulinski was superannuated without further payment. Since 1917 he was also inscribed at the College for Advanced Technology in Vienna ("Technische Hochschule Wien"), but he never graduated, instead he autodidactically attained the VDI-Engineering-Diploma (VDI = "Verein Deutscher Ingenieure"- Association of German Engineers). During 1921-1924 he worked as a development engineer and later as a design engineer for a car factory. In 1925 he set up and ran his own company (radio sale enterprise) and in 1929 an engineering workshop. From 1938 to 1945 he first served as technical staff and later as a design engineer at the Siebel- Flugzeugwerke (Airplane-Factory) in Halle/Saale, Germany. After the Second World War he was employed as a design engineer at different engineering companies in Austria and he died 1974 in Wels. Ulinski's first contact with the topic of space flight occurred during the time period when he was a member of the Austro- Hungarian Army. Ulinski was one of the first in the german speaking part of Europe to publish an article with his ideas about space flight in 1920 (three years before Herman Oberth published his book on travelling into space). The Austrian flight magazine "Der Flug" (The Flight) printed a manuscript deposited by Ulinski at the Academy of Sciences in Vienna (October 1, 1919) in a special edition of December 1920. Ulinski describes in this article a space ship using corpuscular rays as impulse. The energy for accelerating the electrons comes from either solar energy, which has been transformed into electrical energy before, or from the use of "intra-atomic" energy. Unfortunately, the study suffers from some serious errors in the description of the physics involved, but still it can be considered as one of the first to propose the energy gained from solar radiation as a driving power for a spacecraft. During the Twenties another design of a space ship by Ulinski got some doubtful publicity. The space ship consisted of a closed chamber, within the rocket should work. The disagreement of this design with the laws of mechanics (physics) is rather obvious and brought Ulinski into disrepute in the rocket circles of the time. Two years ago the last known work of Ulinski with respect to rocketry was discovered. It is a typewritten manuscript of a talk he gave on March 24, 1941 at a VDI-meeting in Halle/Saale with the title "The problem of rocket flight".
