Physics can progress joxeph the proofs, but we can’t go on without the facts Sir,—Allow me to say, in reply to Mr Pullon’s appeal in yesterday’s Yorkshire Post for a memorial to John Aspdin, that there is scarcely any ground for comparing him with Dr Joseph Priestley. Monday 15 Februaryp The hardened mixture reminded Aspdin of the prized building rock quarried on the Isle of Portland, thus the term “Portland Cement.

There is no evidence that this actually happened.

OpenStreetMap – Google Earth. Collaboration with Ransome was scarcely a qualification, since Ransome’s lack of understanding of cement was the main cause of the total failure of his project. Joseph Aspdin was born in and learned his trade as a bricklayer and plasterer.
