Pegram was born in London and received his first artistic education at the West London School of Art. Already in 1881 and in 1883 he won prizes at the National Art Competitions. In 1881, he entered the Royal Academy schools, where he again won prizes in 1882, 1884, and 1886. In 1887 he left the school and worked until 1891 as assistant to Hamo Thornycroft. He became a member of the Art Workers’ Guild in 1890, an Associate of the Royal Academy in 1904 and finally a Royal Academician in 1922. From 1890, Pegram was commissioned for numerous building decorations and statues. In 1913, he was one of the ten sculptors selected to work on the city hall of Cardiff, for which he sculpted the figure of Llewelyn the Last.
His daughter, Doris Joan Pegram, married the artist and illustrator H. M. Brock.
