Who was Charles Darwin's maternal grandfather?

Charles Darwin's maternal grandfather was Josiah Wedgwood. Wedgwood was the celebrated English potter and industrialist who founded the Wedgwood pottery company and helped transform ceramics into a major modern industry.

Darwin's mother, Susannah Wedgwood, was one of Josiah's daughters. Through her, Darwin inherited the Wedgwood family's strong scientific, industrial, and intellectual connections. Josiah was also a close friend and business associate of Erasmus Darwin, Charles's paternal grandfather, which brought the two families together before Charles was born.

The family connection became even closer when Charles Darwin married his first cousin Emma Wedgwood, another granddaughter of Josiah Wedgwood. Their marriage joined the Darwin and Wedgwood families in the same generation and helped preserve the family's considerable wealth, allowing Darwin to pursue natural history.

A common mix-up is Erasmus Darwin, who was Charles's paternal grandfather. Erasmus was a physician, poet, and early thinker about evolution; Josiah Wedgwood was the maternal grandfather on Darwin's mother's side.
