A German mathematician (1815 to 1897) often called the father of modern analysis. He rebuilt real and complex analysis on a rigorous logical foundation, formalizing continuity and limits, and in 1872 startled the Berlin Academy by exhibiting a continuous function with no derivative at any point, work now known as the Weierstrass function.

Weierstrass was Cantor's teacher in Berlin; no dedicated advisor/student relation type exists on this atlas at claim time (checked dbo.vRelationType), so this is recorded as a general association rather than an invented vocabulary item.
