Henri Poincaré was born to Léon Poincaré and Eugénie Launois in Nancy, France. His father was a professor of medicine at the University of Nancy.

Poincaré began his studies at the prestigious École Polytechnique in Paris, where he excelled in mathematics and physics, laying the foundation for his future career.

Poincaré completed his studies at École Polytechnique and moved on to the École des Mines to train as an engineer, where he continued to pursue his mathematical interests.

Poincaré received his doctorate in mathematics from the University of Paris for his thesis on differential equations, which marked the beginning of his academic career.

Poincaré was appointed to a professorship in mathematics at the University of Caen, where he taught and conducted research, further establishing his reputation in the field.

Poincaré returned to Paris to take up a professorship at the Sorbonne, where he taught a wide range of mathematical and physical subjects, becoming a leading figure in the academic community.

Poincaré married Louise Poulain d'Andecy, with whom he had four children. Their marriage provided a stable and supportive environment for his prolific scientific work.

Poincaré published his groundbreaking paper 'Analysis Situs,' which laid the foundations of algebraic topology, a field that would become crucial in 20th-century mathematics.

Poincaré was elected President of the French Academy of Sciences, a position that recognized his significant contributions to mathematics, physics, and philosophy.

Henri Poincaré died in Paris, France, after undergoing surgery for a pulmonary embolism. His death marked the end of a brilliant career and left a lasting legacy in science and mathematics.
