Sava Kosanovic: The Nephew of Nikola Tesla Who Played a Key Role in Preserving His Legacy (Nikola Tesla with Sava Kosanovic) While Nikola Tesla is known for his revolutionary contributions to science and technology, his family also played an important role in shaping his legacy, with his nephew Sava Kosanovic standing out as a key figure in Tesla’s later years. Sava Kosanovic, born in 1894, was the son of Tesla's sister, Angelina Tesla, and became one of Tesla’s closest relatives and trusted companions (Seifer, 1998). Though he didn’t share Tesla’s brilliance as an inventor, Kosanovic made significant contributions to preserving and promoting Tesla’s work. He is perhaps best known for his efforts in safeguarding Tesla’s legacy after the inventor’s death, ensuring that Tesla’s contributions to science and technology were recognized by future generations (O'Neill, 1944). Sava Kosanovic’s Early Years and Relationship with Tesla Growing up in the Tesla family, Sava Kosanovic was ex...

Nikola Tesla and Nebojša Petrović: The Forgotten Friendship Nikola Tesla’s life and career were shaped by remarkable encounters with scientists, engineers, and inventors from around the world. One such friendship, which has often been overlooked, is his relationship with Nebojša Petrović, a young Serbian inventor whom Tesla worked with in the late 19th century. This partnership, particularly in 1880, played a key role in Tesla’s intellectual development and may have influenced some of his later discoveries. Despite being lost to history, the friendship between Tesla and Petrović is an intriguing chapter in the inventor’s story (Jovanović, 1999). Who Was Nebojša Petrović? Nebojsa Petrović was a brilliant young Serbian inventor, born in 1856, who made a name for himself in the world of electrical engineering during the late 19th century.

Unveiling the Mysteries of Tesla’s “Death Ray”: Was It a Visionary Weapon or Pure Fiction? Nikola Tesla is often remembered for his electrifying contributions to science—such as alternating current, the induction motor, and the Tesla coil. However, among his many eccentric ideas and experiments, one stands out as both a marvel of imagination and a source of controversy: the so-called “Death Ray.” The Origins of Tesla’s Death Ray Tesla first began speaking publicly about this potential weapon in the early 1900s, just after the turn of the century. His public statements about a “teleforce” weapon capable of destroying enemy aircraft or artillery from a distance were made amid the backdrop of geopolitical tension and the arms race. Tesla was vocal about his concerns over the misuse of science for warfare and believed that his invention could serve as a deterrent for global conflict rather than a tool of destruction. In a 1934 interview with The New York Times (Tesla, 1934), Tesla explain...
