Richard Bernard Heldmann was born on 12 October 1857, in North London, to lace merchant Joseph Heldmann (1827–96) and Emma Marsh (1830–1911), a lace-manufacturer's daughter. Heldmann began publishing fiction during 1880, in the form of boys' school and adventure stories for magazine publications. The most important of these was "Union Jack", a quality boys' weekly magazine associated with authors G. A. Henty (1832–1902) and W.H.G. Kingston (1814–80). Henty promoted the young Heldmann to the position of co-editor in October 1882, but Heldmann's association with the publication was ended abruptly in June 1883. After this, Bernard Heldmann published no further fiction under that name, and began to use the pseudonym "Richard Marsh" a few years later.
