Edward John Gregory RA (Southampton 19 April 1850 – 22 June 1909), was a British painter. Gregory's illustrations, which were sometimes signed by both himself and Hall, discovered the variety and ingenuity of his draughtsmanship. He ceased to work regularly for the Graphic about 1875.
Gregory was not a frequent exhibitor at Burlington House. His mark as a painter was first made by an oil-painting, Dawn (now in the possession of John Singer Sargent, R.A.), originally shown at Deschamps' gallery in 1879. Much of his best work appeared at the exhibitions of the Royal Institute of Painters in Water Colours, of which he was elected associate in 1871 and member in 1876. He succeeded Sir James Linton as president in 1898. From 1875 to 1882, his contributions to the Academy were mainly portraits, including that of Duncan McLaren MP, a replica of which is in the Scottish National Portrait Gallery. As early as 1883, he was elected with Macbeth to the associateship, and he became academician in 1898, after the completion and exhibition of his Boulter's Lock: Sunday Afternoon, a work which hardly justified the years of elaboration spent upon it.
