Letters: Sir Arnold Wolfendale obituary

Sir Arnold Wolfendale wrote an article on John Harrison and the invention of his maritime clock (2008) for The Historian, the members' journal of the Historical Association. On making his acquaintance, I discovered that, along with being a physics professor and astronomer royal, he attended the lectures and other activities of the Historical Association branch in Durham.

In 2000 Arnold Wolfendale helped the International Association of Physics Students draw attention to the plight of physics students outside the US and western Europe, often compelled to leave their own countries to find work.
