Gustav Theodor Fechner (1801-1887) was an early pioneer in experimental psychology, founder of psychophysics, and introduced the median into the formal analysis of data. The still-mysterious perceptual illusion where colors are seen in a moving pattern of black and white is still called the Fechner color effect. This "Little Book of Life After Death" tells us "that even though we do nothing wicked, we may neglect to do anything immortal, and therefore our future prospects are as trivial as our performance now or in the past. We shall deserve to be forgotten."
