[ Locker / The Naval Gallery of Greenwich Hospital ]
Edwin Hawke Locker (1777 - 1849) was an English painter and writer as well as administrator of the Royal Naval Hospital, Greenwich (also known as "Royal Hospital for Seamen at Greenwich") — which was not a "hospital" in the modern sense of the word, but essentially a retirement home for British sailors, though it also included an infirmary and a school. It was in existence as such from 1692 to 1869. (Greenwich, by the way, is in the greater London metropolitan area.)
This volume is a collection of portraits and memoirs of some of the chief administrators of Greenwich Hospital, and was first published in 1832 (London: Harding and Lepard); text is from that edition.
The work's only mention of Newfoundlands occurs in the discussion of William Locker, the author's father and a highly regarded naval officer.
The fireside on a winter evening was a scene highly picturesque. . . . His cane, containing a near-sighted glass in its head, rested beside his chair, and a footstool supported his wounded leg, beyond which lay his old faithful Newfoundland dog stretched upon the hearth. (37)
This book was reviewed at some length in Gentleman's Magazine (Supplement to Part 2 of Volume 102; 1832), which quoted a long extract from the discussion of William Locker, including the above passage.
