Gustav Kirchhoff
1824 – 1887
His circuit laws, published at 21, make network analysis routine.
A German physicist who, at 21, published the circuit laws of current and voltage that make network analysis routine — then went on to found spectroscopy and coin the term 'black-body radiation.'
The voltage-divider, bridge, and every multi-node circuit tool here rely on Kirchhoff's laws. Few 21-year-olds have left a longer shadow.
