At the December 2016 meeting of Cambridge Industrial Archaeology Society (CIAS), Brian Jackson recalled his long and fruitful working relationship with the late CIAS Member, Don Unwin.

Brian displayed the square-wheel clock which Don had built and described the teething (no pun intended) troubles which were eventually overcome. Also described with “visual aids” were some of the other clocks which Don had built (e.g. a Harrison H3) as well as Don's wide technical interests outside chronography, including:

  • the design and construction of water pumps for developing countries
  • his role in the Consumers Association (Which Magazine!) through the design and operation of test equipment.

This fascinating meeting closed with reminisces from the members and Brian of Don’s "life and times”. CIAS would be very interested to hear in any potential authors with a technical bent who could write Don Unwin's biography.
