In 1845, Mr. Heavyside succeeded Mr. Dobson, but held the office for a year only, being in turn succeeded by Mr. Thos. Clarke. The number of students at this time was 448.
Mr. George Wallis became Head Master in 1851, and introduced many changes in the organization and work of the school. He resigned in 1857, Mr. D. Raimbach being his successor.
By an agreement between the Society of Artists and the Council of the newly founded Birmingham and Midland Institute, the latter undertook to provide double the existing accommodation for the Society of Arts in their proposed building; and the school was transferred in the summer of 1858 to the rooms which it continued to occupy until last year.
The record of the school from the first seems to be one of continuously increasing success; for in 1864 the number of students had more than doubled, being 939, including elementary and advanced classes.
In its early days the school was much indebted to the Rev. James Prince Lee, M.A., who held the post of Chairman until he was removed to the See of Manchester, and in more recent times to the late Mr. John Henry Chamberlain, Chairman, and Mr. Edwin Smith, Secretary.
In 1875 the whole of the elementary teaching in the evening was transferred to branch classes held in Board Schools.
A most generous offer was made to the school in 1876. An anonymous donor placed the sum of £10,000 at the disposal of the Committee, with a request that it should be chiefly, if not altogether, employed in the improvement of the teaching department, and in the foundation of scholarships or exhibitions.
On the resignation of Mr. Raimbach, the present Head Master (Mr. Edward R. Taylor) was appointed in May, 1877. In the year 1880 a scheme was initiated by a donation of £5,000 from Messrs. Richard and George Tangye, which has resulted in the present Museum and Art Gallery, with its noble collection of pictures and objects of industrial art, the gifts of wealthy citizens to the town. The increasing difficulties under which the School of Art laboured in providing room for the education by which alone these art treasures could be made of use to the town were not lost sight of, and in 1881 the Mayor (Mr. Richard Chamberlain, M.P.) was enabled to announce to the Corporation that land would be given by Mr. Cregoe Colmore, in the centre of the town, on which to build a School of Art, and that Miss Ryland would give £10,000, and Messrs. Richard and George Tangye would also give £10,000 towards the cost of building a School on condition that the Town Council would undertake its management. The result of this generosity is the beautiful building in Margaret Street, the last work of the late Mr. J. H. Chamberlain, who had for many years acted as Chairman of the School, and had taken the deepest interest in its success. It may fairly claim to be one of the best schools of art ever erected. The lighting is bright and cheerful, furnishing in this a contrast to most of such institutions; and the accommodation, especially for the modelling classes and those for studies bearing on design, is most ample, and a great improvement on that given in the old premises.
