No Binding. Zustand: Very Good. Two manuscripts from Jesse Ramsden's workshop, 1786 and 1788. [FIRST MANUSCRIPT] Note addressed to 'Mr Torre'. Torre must (owing to the date) be the optician Anthony Torre, whose workshop was located just to the south of Ramsden's Piccadilly workshop at Pall Mall. The note is clearly a matter of some urgency. Ramsden requests payment of 25 Guineas (equivalent to upwards of £2,000 today) and claims he will deliver his 'work' within half an hour. This raises a number of points of historical interest. For example, was Ramsden supplying parts or whole instruments for Torre to retail? This is certainly possible but as this is the first known connection between Ramsden and Torre the question has not been explored. Second, why the urgency? Was Torre really expected to pay this huge sum just to receive the work in a timely manner? The note is one a single sheet, folded in at the corners and sealed to make an impromptu self-envelope. Clearly this was hand delivered by one of Ramsden's assistants, either to Torre, waiting at his door, or to Torre's nearby workshop. An incredible glimpse into the hurly-burly of instrument making. [SECOND MANUSCRIPT] Receipt made out to Marsilio Landriani. A glimpse of Ramsden's notorious slow workmanship is given here, as the sale of the opera glasses ('Bellows with Col[oure]d Glasses') took place on 30 October 1788, and the repair was dated 27 November 1788. We know of no Ramsden opera glasses that meet this description, though the type is common enough and he may have been acting as retailer. Both documents in Ramsden's hand, bearing his name - #1 with the distinctive 'R' found on some of his instruments. Jesse Ramsden is well known as the premier instrument maker of his generation. He is famed for his astronomical and surveying instruments, and particularly the accuracy of his divided scales, for which he invented a dividing machine in the 1770s. He is one of the few instrument makers subject to full biographical treatment, in Anita McConnell's masterful 2007 work. As McConnell acknowledges, there are very few extant documents relating directly to Ramsden's life and work. There are no personal papers or business papers. Instead McConnell's biography draws on the evidence surviving in his clients' papers, and on Ramsden's own published accounts of his inventions. The only Ramsden manuscript we can locate on the market is a letter offered by Tesseract in 2008 (Catalogue 86, Nos 15, $6,500). Both manuscripts in very good condition, on good laid paper: #1 appears to be written on a fragment cut from a larger sheet, but is complete in itself; with original folds making a self-envelope 'M. Torre' and '1786 / Mr Ramsden' on the reverse. Remnants of sealing wax to one corner. #2 with some edge wear but also in excellent condition; partial watermark visible; early note about Ramsden to the rear. Signed by Author(s).
