Albert Einstein's personal life was as complex as his scientific work, marked by numerous relationships both inside and outside his two marriages. While he enjoyed female attention, letters suggest he could be emotionally distant. His first marriage to Mileva Marić, an intellectually gifted woman who some scholars believe contributed to his early work, produced three children. The marriage deteriorated due to Einstein's focus on research and Mileva's domestic role, leading to their divorce in 1919.
