Spiridon Gopčević (junior), pen name Leo Brenner (; 9 July 1855 – 1928) was a Serbian-Austrian astronomer and historian born in Trieste. Life He was named after his father, Spiridon, who was a great shipowner in Trieste, then Austrian Littoral (modern Italy), but had originated from the village of Podi near Herceg Novi, in Boka Kotorska (modern Montenegro), then a part of the Austrian Empire. After the death of his father, when Spiridon was a boy, he was sent to Vienna to be educated. He attended the Theresianum (1861-1865) and Stiftsgymnasium Melk (1865-1869) at Melk in Austria. Following the death of his mother, he became a journalist by trade. He regarded himself first and foremost as a Serb, and that drove him to participate in the 1875 uprising in Herzegovina, and the following year to witness the Montenegrin-Ottoman War (1876-78), and participate in an insurrection in 1882 against the Habsburgs in southern Dalmatia, where he was arrested with Arthur Evans, who was a reporter for the Manchester Guardian at the time. Gopčević worked in these years as a war correspondent in the Balkans, and also travelled to Siberia, North America, North Africa and the Middle East. He even had a chance in London to meet William Gladstone in 1879. Gopčević entered the Serbian foreign service and served as diplomatic attaché in Berlin (1886-1887) and Vienna (1887-1890). In 1891 he went back to his family estate in Trieste, where he continued to write as a journalist for several German-language newspapers. In 1893 Gopčević spent time in jail due to some of his articles against the Austro-Hungarian government, and decided to end his journalistic career. Astronomy became the dominant interest in Gopčević's life and, to a most unusual extent, his work was his life and his life was his work. In 1893 he founded an observatory "Manora-Sternwarte" in the town of what is now called Mali Lošinj in present-day Croatia. This observatory was named for his wife, a wealthy Austrian noblewoman. At this observatory, Spiridon used the 17.5 cm refractor telescope at the observatory to make observations of Mars, the rings of Saturn, and other planets. However he would eventually close the observatory in 1909 due to financial problems, and the telescope was offered for sale. From 1899 until 1908 he was the founder and editor of the Astronomische Rundschau, a popular scientific journal. He spent several years in America before returning
