This is the location of Ethel Dickens's first independent type-writing office in which she was the sole proprietor. She opened this office at the end of 1887, possibly as early as October and certainly by December. It was located above the offices of All the Year Round, the literary miscellany magazine started by her grandfather, Charles Dickens, and inherited by her father, Charles Dickens, Jr. (better known as Charley Dickens). Ethel began using the "two rooms formerly used for editorial purposes by her grandfather, Charles Dickens," ("Type-writing Offices--2") but soon found she needed more office space, so her business then occupied the upper floors of this location until sometime late in 1891. She is still advertising at this location in March, 1891, and the London Phonographer publishes an article on her business ("Type-writing Offices--2") in July of 1891, noting her shared premises with All the Year Round. Later in 1891, however, her office appears to have moved to 3 Tavistock Street according to her listing in the Post Office Directory.
The building containing 26 Wellington Street is located at the corner of what is now a northeasterly extension of Tavistock Street (and which was then York Street) and Wellington. It stands across Tavistock Street from one of Ethel Dickens's future office sites, 28 Wellington Street.
