Rudolf Flesch

Rudolf Franz Flesch (8 May 1911 – 5 October 1986) was an Austrian-born naturalized American writer (noted for his book Why Johnny Can't Read), and also a readability expert and writing consultant who was a vigorous proponent of plain English in the United States.[1] He created the Flesch Reading Ease test and was co-creator of the Flesch–Kincaid readability tests. Flesch advocated use of phonics rather than sight reading to enable students to sound-out unfamiliar words.[1]^{[dead link]}
