About the author

Born in 1840 and raised in Greenwich, he began working at the Royal Observatory as a teenager and later became an assistant there. He worked on observation and instrument duties, took part in early spectroscopic work, and was trusted with the care of the observatory library and manuscripts.

He is best remembered for The Moon: Considered as a Planet, a World, and a Satellite, written with James Nasmyth and first published in 1874. The book became his best-known legacy, bringing detailed lunar ideas and imagery to a wide readership.

After marrying Ellen Penn in 1868, he left the observatory in 1872 to join the family engineering firm John Penn & Sons. He died on October 17, 1899. Although portraits of him are hard to confirm, his name lives on in the lunar crater Carpenter.
