Pearson was an original member of CR Ashbee’s Guild of Handicraft starting in 1888. Pearson was kicked out of the Guild for keeping his own shop on the side, rehired & later resigned to join the Newlyn Industrial Class. He also worked for the designer & ceramicist William De Morgan which is where many of his fanciful themes in repousse are inspired. He is considered one of the finest repousse metalsmiths of the period. His shop remained active until after the turn of the century, most pieces are dated.
