Tribute to our esteemed colleague and friend

On behalf of the International Colour Vision Society, we send condolences for Professor André Roth. Professor Roth served as President of the Society, and guided our transition from a mainly clinical group to an international society covering many disciplines. Much respected as an authority on colour-vision testing, in 2003 he received our primary award, the Verriest Medal. We remember his kindness, his wisdom, and his ability always to find the right word for the occasion.
