Theodor Otto Diener (28 February 1921 – 28 March 2023) was a Swiss-American plant pathologist. [1] In 1971, he discovered that the causative agent of the potato spindle tuber disease is not a virus, but a novel agent, which consists solely of a short strand of single-stranded RNA without a protein capsid, eighty times smaller than the ...
