Nikola Tesla had a total of four siblings. He was the fourth of five children in his family. His siblings included three sisters named Dane, Milka, and Angelina, and one brother named Virgil. Unfortunately, Tesla’s brother Virgil died at a young age in a tragic accident, which deeply affected Tesla throughout his life.
This family background, especially the loss of his brother, helped shape Tesla’s personality and drive. His family was quite supportive of his education and interests, particularly in science and technology. Tesla’s relationship with his sisters also had a significant impact, as he maintained a lifelong connection with them, especially with his sister Marika, who was said to be particularly fond of him.
