The festival's Science Medal was awarded to Deri Tomos, Llanllechid, for his lifelong contribution to science through the medium of Welsh.
Originally from Cardiff, Deri came to Bangor as a research fellow in the university after graduating and completing his doctorate at Cambridge. He was appointed a lecturer in Bangor in 1985, and within 10 years had received a Personal Chair at the University. He has also spent time as a research fellow in Adelaide, Utah and Heidelberg. He was responsible for developing much of the Welsh-medium provision for these degree courses, although he faced considerable opposition at the time.
Accepting the award he said he felt "humbled to be among the giants of science" who had received the award since it was introduced at the Eisteddfod.
