April 22nd is Earth Day:

And Vladimir Lenin’s birthday:

They lived in western Europe after 1900. At the 1903 meeting in London of the Russian Social-Democratic Workers’ Party, he emerged as the leader of the Bolshevik faction. In several revolutionary newspapers that he founded and edited, he put forth his theory of the party as the vanguard of the proletariat, a centralized body organized around a core of professional revolutionaries; his ideas, later known as Leninism, would be joined with Karl Marx‘s theories to form Marxism-Leninism, which became the communist worldview.

It an “odd” coincidence…
