The first reference in newspapers to a Harrison, photographer, at this address is an advert and an article in the April 7th 1906 edition of the Eastern Argus. The article refers to his "well-known establishment". Adverts continue in 1906, and there is a 1908 mention of him acting as photographer at a golden wedding.
In earlier years the address is associated with "apartments to let" ads which end in 1892.
The photographer is Henry Harrison, still at the address in the 1921 census when he is aged 45, and also at the address in 1911. I haven't yet managed to find him in the 1901 census.
