On Giants' Shoulders was written in 1998 by Melvyn Bragg. The book was assembled after a series of interviews Bragg had with current scientists about the world's greatest scientists such as Archimedes, Isaac Newton and Einstein. Bragg, who brands himself as a "non-scientist", conducted these interviews on BBC Radio 4 for other non-scientists. The book looks at the notion of being a "genius" and through discussions with 20th-century scientists explores the extent to which the great scientists of history were geniuses.
