Early Life and Education
- Born into a Catholic family in Prague.
- Studied philosophy, mathematics, and physics at the Charles University in Prague.
- Ordained as a Catholic priest in 1805.
Career and Major Achievements
- Appointed Professor of Philosophy of Religion at the Charles University in Prague in 1805.
- His pacifist and socially critical views led to his dismissal from the university in 1819 under pressure from the Austrian authorities.
- Spent the remainder of his life in private study and writing.
- Pioneered rigorous mathematical analysis, independently anticipating many concepts later developed by Cauchy, Weierstrass, and others.
- Made significant contributions to logic, set theory, and the foundations of mathematics.
- The 'liceo bernard bolzano biography' would be incomplete without mentioning his work in social critique and philosophy, though less widely recognized than his mathematical achievements during his lifetime.
Notable Works
- Der binomische Lehrsatz (1816)
- Rein analytischer Beweis (1817)
- Wissenschaftslehre (Theory of Science) (1837)
- Paradoxien des Unendlichen (Paradoxes of the Infinite) (1851, published posthumously)

Legacy and Impact
Bernard Bolzano's work was largely unrecognized during his lifetime but gained considerable influence in the late 19th and early 20th centuries. He is now considered a precursor of modern mathematical analysis and a key figure in the development of logic and set theory. His philosophical insights, though initially controversial, have also been re-evaluated and appreciated for their depth and originality. His rigorous approach to mathematics and logic laid the groundwork for future generations of researchers.
