Gordon and Liz Roberts from Derbyshire, who have re-published all of Robert Recorde's mathematical books, were delighted with the number of people who visited Tenby Museum to take part in the week-long event, Read Robert Recorde.

They have been explaining how and why they came to undertake the complicated task of bringing Recorde back to prominence through the reproduction of his books whilst helping visitors to read and understand the texts and to explain Recorde's method of teaching mathematics.

Recorde, born in Tenby in 1510, is credited with inventing the equals (=) sign.

Gordon first became interested in the subject whilst studying for a maths degree with the Open University, which included studying the history of mathematics.

This led him to Tenby Museum and Art Gallery to undertake research, which fired his interest in this remarkable son of Tenby.

Together with his wife Liz, who typed all the texts, he set about teaching himself book-binding and reproducing the books for his own interest.

The museum is delighted to have been presented with copies of these hand-made volumes, which are invaluable for researchers.

When attending the 450th Robert Recorde Memorial Conference at Gregynog in 2008, so much interest was shown in these reproductions that Gordon and Liz were persuaded to go into production on a commercial basis.

Many universities, colleges and academics have grasped the opportunity to own one of these unique works.

Visitors to the museum had a very enjoyable experience talking to them about Robert Recorde and some also placed orders for the books, which are printed on demand.

This event was timed to coincide with the '2010-1510 = Robert Recorde' art exhibition currently on show at the museum.

Over 50 artists have produced works of outstanding merit in many different mediums from paintings to constructions, ceramics and mixed media to photography and glass to celebrate the life and myriad achievements of Recorde.
