In existographies, Dmitri Mendeleyev (1834-1907) (IQ:175|#240) (Murray 20:16|C) (CR:21) was a Russian chemist noted for his 1869 construction of the periodic table of elements, which after struggling with for some time prior, he found say the table in a dream: [1]

“I saw in a dream a table where all the elements fell into place as required. Awakening, I immediately wrote it down on a piece of paper.”

Of curiosity, this is similar to German chemist August Kekule’s famous 1865 dream about a snake circling around to bite its tale as the visualization of the structural model for Benzene. Mendeleyev's table that he wrote down, containing a total of 66 known (and some unknown) elements, is shown below:

Mendeleev is also credited for scientific justification of the "optimal" ratio of alcohol of 40% (80 proof) used in Russian vodka. (Ѻ)

“No law of nature, however general, has been established all at once; its recognition has always been preceded by many presentiments.”
