War and revolution reshape Hua's mathematical career

She assigned and reviewed demanding aeronautical calculations while advocating for staff members' opportunities.

Anticipating automation, she learned programming and helped colleagues shift from hand calculation to digital computing.

Vaughan's achievements occurred within racially separated facilities and job classifications that obscured Black women's contributions.

Largely self-taught after leaving school, Hua became one of China's most influential twentieth-century mathematicians.

His research addressed Waring's problem, exponential sums, prime numbers and the geometry of numbers.

He promoted optimization and operational research in factories and agriculture, connecting advanced mathematics with mass development programs.

Turing became a founder of theoretical computer science and made influential contributions to logic, cryptanalysis and artificial intelligence.

His abstract device clarified what it means for a procedure to be mechanically calculable.

At Bletchley Park, Turing and a large team used logic, statistics, engineering and intercepted communications against Nazi Germany.

His 1952 conviction and forced hormonal treatment show how a state could exploit mathematical talent while criminalizing the mathematician.
