author
A father-and-son writing team hid behind this single pen name, creating imaginative science-fiction adventures for young readers. Their best-known work is the long-running Time Machine series first published in Boys' Life.

by Donald Keith
Donald Keith was the shared pseudonym of Donald Monroe and his son Keith Monroe. According to widely available reference sources, the name is best known for the Time Machine stories, which appeared in Boys' Life over several decades and were later gathered into books including Mutiny in the Time Machine and Time Machine to the Rescue.
That unusual collaboration gives the name a special place in mid-20th-century children's science fiction. The stories mixed fast-moving adventure with time-travel ideas, and later entries were credited to Keith Monroe alone.
