I am familiar with Waller's famous print of Skipton and here is a link to the catalogue of oil paintings in public collections in the UK (there are currently around 104,000 paintings listed of 200,000 which are being added throughout 2012).

WORTHIES OF OLD SKIPTON. 263
RICHARD WALLER,
Artist.
Only during the present year, 1882, has this notable native of Skipton
passed away. Richard Waller was born in 1811. He was very early
sent to a school in Newmarket-street, conducted by Mr. James Hall, the
parish clerk, and at the age of fifteen was apprenticed to Mr. Johnson, a
coach builder, who carried oii business in Coach-street. At a very early
age Waller showed a strong passion for painting, and although this
apprenticeship was distasteful to him, it was a step towards that higher
calling he was afterwards to follow. While yet young he painted a
picture called " Skipton in the Olden Time." This work was stolen, and
it has never been restored. After passing some time as a coach-painter,
Waller confined himself to the painting of the heraldic work connected
with the establishment. On the completion of the term of his apprentice-
ship. Waller left Skipton for Manchester, and there studied painting of a
higher kind. Here he opened a studio. At first he devoted himself
to landscapes and imaginative subjects, but at a later period he
turned his attention to portrait-painting, and it was in this branch of the
art that he ultimately made his name so celebrated. After four years'
residence in Manchester, Waller returned to Skipton, and executed a
second picture of the main street of the town, taken from Caroline
Square. A third picture of the same was produced some time later, and
with the title " A View of Skipton-in-Craven" was engraved by Baron
Friedel, the noted London engraver. Mr. Waller stayed in Skipton
until 1840, being kept well employed during the time, but in that year
he went to London, where he remained nine months, afterwards visiting
Keighley and Bradford for short periods. In the latter place he made
the acquaintance of a number of persons of literaiy and artistic tastes.
Mr. Waller's next removal was to Leeds, where he opened rooms in
Park Square. While here he painted a picture of Mr. Edward Baines,
father of Sir Edward, which added greatly to the fame his genius had
akeady won him. It was from this picture tliat Mr. Noble Bohnes
afterwards framed the statue of Mr. Baines which is now in the Leeds
Town Hall.
Again changing his place of abode, Mr. Waller went to London, where
he enjoyed the companionship of many prominent figures in the literary
and artistic world — among them Dickens, Thackeray, Lemon, Douglas
Jerrold, Woolger, and Alfred Melon. While in the capital he painted
many pictures from life. Several of his uudo figures, clever as specimens
of flesh-painting, were hung in the Royal Academy. In 1846 Waller
painted a successful picture of Garibaldi — one of seven painted during
the Hero of Caprera's visit to England, and, as the General declared, the
best. Another of Waller's notable early portraits was that of Earl
Cairns, which attracted considerable attention at the exhibition held in
the Cloth Hall Yard, Leeds. This picture was passed to be hung in
the Royal Academy, and it was named in the catalogue, but by some
accident was left out of the exhibition. Many other clever portraits
Waller executed in the coiirse of his laborious career. Indeed, it has
been said that there is scarcely a family of standing in the county but
possesses some work from his hand. One of his works is " Crom.
well's soldiers in Skipton Church."
But, in addition to being a successful artist, Waller was an
indefatigable mechanician and an inventor. It would not be wrong
to say that half his life was spent in perfecting several scientific
discoveries and improvements in mechanism. The discovery of a
new motive power for engines was one of the objects which he
most steadfastly pursued, and one of the schemes on which he set
most store was incomplete at the time of his death. At a time when
the thought of constructing expensive railways had occurred to only few
persons, Mr. Waller was labouring to apply the steam power used in
mills to road conveyances, and upon this scheme he spent much
valuable time and money. Waller always kept a mechanics' shop in
operation, carrying on experiments while he was working at the easle to
supply the necessary funds. The artist died June 25th, 1882, aged
71 years.
