Real name: Denys James Watkins-Pitchford

Denys James Watkins-Pitchford MBE (25 July 1905–8 September 1990) was a British naturalist, children's writer, and illustrator who wrote under the pseudonym "B.B.".

Denys Watkins-Pitchford was born in Lamport, Northamptonshire on the 25th July 1905. He was the second son of the Revd. Walter Watkins-Pitchford and his wife, Edith. His elder brother, Engel, died at the age of thirteen. Denys was himself considered to be delicate as a child, and because of this was educated at home, while his younger twin, Roger, was sent away to school. He spent a great deal of time on his own, wandering through the fields, and developed a love of the outdoors, which was to influence his writing.
His daughter Angela leads the BB Society dedicated to her father.
