Date exact date unknown; Originally published in an article by Johan Kjeldahl in Meddelelser fra Carlsberglaboratoriet (Reports from the Carlsberg Laboratory), Volume 2 (1883-1888)
Source Snapshot from a digital PDF reproduction (D. Thorburn Burns: Kjeldahl, the Man, the Method and the Carlsberg Laboratory. In: Analytical Proceedings. 21/1984. Royal Society of Chemistry, p. 210–214, ISSN 0144-557X)
Author According to the paper by D. Thorburn Burns, the image was created by "J.F. Rosenstand", which apparently refers to Danish artist Johan Frederik Rosenstand (1820-1887) who was a well-established xylographer of his time (see also the signature "Rosenstand" on the bottom left of the image)
