Description of Jens Olsen's Copenhagen Astronomical Clock

[Bill Ward]

Prof. Denis Roegel, of France, has recently embarked on a project to describe the Copenhagen Astronomical clock, built by Jens Olsen and inaugurated by the King of Denmark in 1955. This clock has been described in a book of 1957 by Otto Morgenson, in Danish and English, but that book is somewhat incomplete and is now rare. The portal to the installments of this project are at github here:

Jens Olsen's clocks

Prof. Roegel promises more photos and drawings, and explanations of the science behind the gear ratios. The postings are in English.
Happy Holidays!
