    Re: Need Grubb Lens Expertise

    Grubb 'C' Patent Lenses has a 3" diameter glass. 'A' was 2" and they went up to 'G' (6"). There were smaller lenses for stereo use, Doublets (see below) and Petzvals. Later Grubb's were by Howard, Thomas's son and varied with many being Doublets. Still working on a history of Grubb lenses but its looking as though Thomas Grubb was the first maker to produce the Doublets which would become better known as Rapid Rectilinear lenses, in 1864 ..... tbc

    This has already been noted on the literature - mostly in the 19th Century - in Trail Taylor’s collected articles. Grubb is reported as being annoyed, but didn’t get involved in the Steinheil/Dallmeyer debate, as far as I know.

    This collection as presented is slightly less than two feet across, maybe 21 or 22 inches.

    Thanks Paul

    My collection is as follows, Front Row from left to right 482 C Aplanatic, 582 C Aplanatic, 3631 Ax Aplanatic. Back Row from left to right 509 Aplanatic (slightly smaller than C) with helicoid, 2591 D Aplanatic, 4039 C Aplanatic and 5045 Aplanatic Doublet. Some of the washer stops I have received with the lenses are shown at the front. I also have an original Waterhouse stop for the Doublet.

    I have taken excellent photographs using the small Ax with a bellows to focus in front of a digital camera. I have some old wooden cameras which I may eventually use to shoot 4 x5 sheet film using these lenses when I can get the cameras adapted. Covid is not helping that project.

    By this time Thomas Grubb was heavily involved in building the "Great Melbourne Telescope" and would have been very busy with what was a huge and highly prestigious (and probably lucrative ) project when Dallmeyer's patent was granted. His agent Solomon did detail the fact that the RR had already been made and said so in the press but it appears that Grubb simply never pursued the matter and Dallmeyer was credited (wrongly) by many with the invention of the Rapid Rectilinear from then on. Kingslake's book perpetuated the myth because Kigslake must not have had access to original copies of the photographic press, many of which are available online today. I have tracked down the existence of 5 copies of Grubb's original Doublet, one of which I own. I also have details of the day on which it was made (25-06-1865). However the first Doublet was made by Thomas Grubb on 09-09-1864 so it was in production well before Dallmeyer's patent.

    This is an example of an engraving on Grubb Patent 2215 Patent Doublet from pgk's collection. He was unable to upload it himself. It is also shown here in a piece about my collection and engravings on the British Photographic History website.

    The same question is asked here about whether there is evidence of such 'lens signing' by other manufacturers. There is a reference here to the signing of Darlot lenses with 'Darlot Paris 10'.
