No, Nikola Tesla never married.
Tesla dedicated his life to his inventions and scientific pursuits, believing that marriage and family life would hinder his ability to focus on his work. He consciously chose a life of celibacy and devoted himself entirely to his research and innovations. He famously stated that an inventor should resist distractions such as relationships to fully immerse themselves in their work. While he never married, anecdotes suggest he formed deep connections with certain individuals, particularly a white pigeon he considered a muse.
