This is to be expected as patents filed this early in the UK are stored in hard copy at the British Library and not scanned into the online archives. The advert above from December 1872 was as early a reference as I could find which actually predates the various patents below by some years.
This isn’t a rabbit hole I fancy going down, but given as this one was made by Wolff, it piqued my interest. As it turns out, there is a whole world of collectors out there who are all about vintage drawing instruments. I admit, I knew nothing about a Spectrograph or a Limnoscope until very recently. Note that at this point in time (July 1874), Wolff was the sole licensee and manufacturer.
This isn’t an appalling typo on my part indulge me, and I’ll get there, I promise. Tangentially, it appears that I have developed an unintentional Wolff ‘shrine’ in the pencil room on reflection, not totally a bad thing.įirst things first – I am aware that the advert above refers to the ‘Spectrograph’ whilst I have referred to the ‘Limnoscope’ in my post title. I have highlighted my penchant for all things ‘Wolff’ before and so when this item came across my desk I realised I would get as much fun from investigating it, as I would from actually using it not that I plan on using it much anyway – this item falls firmly into the ‘display item’ category. I don’t intend on doing this too often, however, should I come across something manufactured and/or marketed by any of my favourite pencil makers, it might find its way onto this blog. This post is a slight segue from my normal ‘pencil specific’ posts, towards a ‘pencil-adjacent’ post.
