As with animated cartoons, the best children’s books are ones that satisfy both the children and the adults. Paul Elder published a number of innovative children’s books, but perhaps the most delightful is How To Tell the Birds From the Flowers by Robert Williams Wood, which appeared in 1907.
There is no traditional typesetting in the book; everything was drawn and lettered by Wood. Each page contains drawings of a bird (for example, the catbird) and a flower (the catnip), plus an amusing poem on how to distinguish them. It’s a perfect bedtime storybook.
Robert Williams Wood (1868-1955) was a professor of physics at Johns Hopkins University from 1901 until his death. He specialized in optics and has been described as the “father of both infrared and ultraviolet photography”. He invented a device now called “Wood’s lamp,” which radiates only ultraviolet light and is used in dermatology to diagnose certain skin conditions which fluoresce under ultraviolet wavelengths. He also co-wrote two science fiction books with Arthur Train, The Man Who Rocked the Earth and The Moon Maker.
Although the cover says “Denatured Series No. 23”, that name was concocted for this book and there are no earlier “denatured” titles. Wood continued the series in 1908 with Animal Analogues as Denatured Series No. 24, but he wrote no further books like it.
