Susan Mary Shaw (née Mahon; 12 August 1932 – 13 June 2020) was a British publisher and the founder of the Type Museum in London.

She founded the Merrion Press, which in 1960 published Wolperiana which featured drawings made by Charles Mozley of Berthold Wolpe.

The museum curates the manufacturing plants of type founders and letter makers in a building that was once an animal hospital.

[4] The Heritage Lottery Fund came to her aid in 1996 so that the machinery and equipment of Stephenson Blake and Robert DeLittle could be loaded up and sent to South London.

[1] The museum now has substantial collections from the Sheffield typefounders Stephenson Blake, the York wood letter makers Robert DeLittle and Monotype.

[5] In 2000, she completed the work that she had been given by the Roxburghe Club to publish a facsimile copy of The Great Book of Thomas Trevilian in two volumes, edited by Nicolas Barker.
