Charles Almanzo Babcock

Charles Almanzo Babcock (1847 1922[1]) was a late-nineteenth-century superintendent of schools in Oil City, Pennsylvania.[2][3] He is credited[3] with launching Bird Day, a day to celebrate birds in American schools, on May 4. The first Bird Day was celebrated in Oil City schools in 1894,[4] and by 1901 the practice was well established.[5] His wife was the author Emma Whitcomb Babcock.

Notes

gollark: Well, it's probably fine, as you can't just set the frequency of light arbitrarily precisely.
gollark: Oh dear. Apparently frequency is in fact continuous.
gollark: Due to uncertainty things non-[HG]Tech™ entities cannot, as far as I know, measure light and whatever to arbitrary precision, so I assume they can't create it to that either.
gollark: No, there are physics reasons too. Something something planck length/time/etc.
gollark: (sum the wave thingies thingied with intensity and transform it and get the function of frequency)
