As to priority of application, the following letter ought to settle that point:—
“Sir,—My hunting has at length proved successful. In the enclosed book you will find notes respecting the paper pulp, albumen, tanno-gelatine, and collodion. You will therein see Mr. Archer’s notes of iod-collodion in 1849. You may wonder that I could not find this note-book before, but the numbers of papers that there are, and the extreme disorder, defy description. My head was in such a deplorable state before I left that I could arrange nothing. Those around me were most anxious to destroy all the papers, and I had great trouble to keep all with Mr. Archer’s handwriting upon them, however dirty and rubbishing they might appear, so they were huddled together, a complete chaos. I look back with the greatest thankfulness that my brain did not completely lose its balance, for I had not a single relative who entered into Mr. Archer’s pursuits, so that they could not possibly assist me.
“Mr. Archer being of so reserved a character, I had to find out where everything was, and my search has been amongst different things. I need not tell you that I hope this dirty enclosure will be taken care of.
“The paper pulp occupied much time; in fact, notes were only made of articles which had been much tried, which might probably be brought into use.—I am, sir, yours faithfully,
“J. Hogg, Esq.
If the foregoing is not evidence sufficient, I have by me a very good glass positive of Hever Castle, Kent, which was taken in the spring of 1849, and two collodion negatives made by Mr. Archer in the autumn of 1848; and these dates are all vouched for by Mr. Jabez Hogg, who was Mr. Archer’s medical attendant and friend, and knew him long before he began his experiments with collodion—whereas I cannot find a trace even of the suggestion of the application of collodion in the practice of photography either by Gustave Le Gray or J. R. Bingham prior to 1849; while Mr. Archer’s note-book proves that he was not only iodizing collodion at that date, but making experiments with paper pulp and gelatine; so that Mr. Archer was not only the inventor of the collodion process, but was on the track of its destroyer even at that early date. He also published his method of bleaching positives and intensifying negatives with bichloride of mercury.
Frederick Scott Archer was born at Bishop Stortford in 1813, but there is little known of his early life, and what little there is I will allow Mrs. Archer to tell in her own way.
“Dear Sir,—I do not know whether the enclosed is what you require; if not, be kind enough to let me know, and I must try to supply you with something better. I thought you merely required particulars relating to photography. Otherwise Mr. Archer’s career was a singular one: Losing his parents in childhood, he lived in a world of his own; I think you know he was apprenticed to a bullion dealer in the city, where the most beautiful antique gems and coins of all nations being constantly before him, gave him the desire to model the figures, and led him to the study of numismatics. He worked so hard at nights at these pursuits that his master gave up the last two years of his time to save his life. He only requested him to be on the premises, on account of his extreme confidence in him.
“Many other peculiarities I could mention, but I dare say you know them already.
“I will send a small case to you, containing some early specimens and gutta-percha negatives, with a copy of Mr. A.’s portrait, which I found on leaving Great Russell Street, and have had several printed from it. It is not a good photograph, but I think you will consider it a likeness. I am, yours faithfully,
“J. Hogg, Esq.
Frederick Scott Archer pursued the double occupation of sculptor and photographer at 105, Great Russell Street. It was there he so persistently persevered in his photographic experiments, and there he died in May, 1857, and was interred in Kensal Green Cemetery. A reference to the report of the Committee will show what was done for his bereaved family—a widow and three children. Mrs. Archer followed her husband in March, 1858, and two of the children died early; but one, Alice (unmarried), is still alive and in receipt of the Crown pension of fifty pounds per annum.
While the collodion episode in the history of photography is before my readers, and especially as the process is rapidly becoming extinct, I think this will be a suitable place to insert Archer’s instructions for making a soluble gun-cotton, iodizing collodion, developing, and fixing the photographic image.
The sulphuric acid and the nitre were mixed together, and immediately the latter was all dissolved, the gun-cotton was added and well stirred with a glass rod for about two minutes; then the cotton was plunged into a large bowl of water and well washed with repeated changes of water until the acid and nitre were washed away. The cotton was then pressed and dried, and converted into collodion by dissolving 30 grains of gun-cotton in 18 fluid ounces of ether and 2 ounces of alcohol—putting the cotton into the ether first, and then adding the alcohol; the collodion allowed to settle and decanted prior to iodizing. The latter operation was performed by adding a sufficient quantity of iodide of silver to each ounce of the plain collodion. Mr. Archer tells how to make the iodide of silver, but the quantity is regulated by the quantity of alcohol in the collodion. When the iodized collodion was ready for use, a glass plate was cleaned and coated with it, and then sensitised by immersion in a bath of nitrate of silver solution—30 grains of nitrate of silver to each ounce of distilled water. From three to five minutes’ immersion in the silver bath was generally sufficient to sensitise the plate. This, of course, had to be done in what is commonly called a dark room. After exposure in the camera, the picture was developed by pouring over the surface of the plate a solution of pyrogallic acid of the following proportions:—
After the development of the picture it was washed and fixed in a solution of hyposulphite of soda, 4 ounces to 1 pint of water. The plate was then washed and dried. This is an epitome of the whole of Archer’s process for making either negatives or positives on glass, the difference being effected by varying the time of exposure and development. Of course the process was somewhat modified and simplified by experience and commercial enterprise. Later on bromides were added to the collodion, an iron developer employed, and cyanide of potassium as a fixing agent; but the principle remained the same from first to last.
When pyrogallic acid was first employed in photography, it was quoted at 21s. per oz., and, if I remember rightly, I paid 3s. for the first drachm that I purchased. On referring to an old price list I find Daguerreotype plates, 21⁄2 by 2 inches, quoted at 12s. per dozen; nitrate of silver, 5s. 6d. per oz.; chloride of gold, 5s. 6d. for 15 grains; hyposulphite of soda at 5s. per lb.; and a half-plate rapid portrait lens by Voightlander, of Vienna, at £60. Those were the days when photography might well be considered expensive, and none but the wealthy could indulge in its pleasures and fascinations.
While I lived in Glasgow, competition was tolerably keen, even then, and amongst the best “glass positive men” were Messrs. Bibo, Bowman, J. Urie, and Young and Sun, as the latter styled himself; and in photographic portraiture, plain and coloured, by the collodion process, were Messrs. Macnab and J. Stuart. From the time that I relinquished the Daguerreotype process, in 1857, I devoted my attention to the production of high-class collodion negatives. I never took kindly to glass positives, though I had done some as early as 1852. They were never equal in beauty and delicacy to a good Daguerreotype, and their low tone was to me very objectionable. I considered the Ferrotype the best form of collodion positive, and did several of them, but my chief work was plain and coloured prints from collodion negatives, also small portraits
