Mar 10, 2026 Jordana Cepelewicz, math editor and science journalist who traces the history of mathematical ideas, guides a deep dive into the Cantor–Dedekind story. Short scenes cover Cantor’s 1874 paper and controversies, Kronecker’s campaign, a researcher’s hunt for missing letters, the 1873 Dedekind proof discovery, and how myths about lone genius and credit shape math history.

Episode notes
Cantor's 1874 Breakthrough And The Dedekind Connection
- Cantor's 1874 paper introduced the idea that infinity has different sizes and reshaped mathematics.
- Georg Cantor published landmark results but drew crucial ideas from correspondence with Richard Dedekind without credit, creating historical controversy.
Kronecker's Campaign Against Cantor
- Opposition from influential mathematician Leopold Kronecker deeply harmed Cantor's career and reputation.
- Kronecker attacked Cantor's ideas as corrupting math, blocked positions, and limited Cantor's publications, contributing to his decline.
Cantor's Personal Decline Amid Mathematical Recognition
- Cantor suffered severe depression and was hospitalized repeatedly, dying in a sanatorium in 1918.
- His decline coincided with the rise of set theory as mathematics' foundational language, which he largely did not see.
