- Karl Marx (1818–1883) is often treated as a revolutionary, an activist rather than a philosopher, whose works inspired the foundation of many communist regimes in the twentieth century. It is certainly hard to find many thinkers who can be said to have had comparable influence in the creation of the modern world.
- Luther Burbank (Wikipedia)
Luther Burbank (March 7, 1849 – April 11, 1926) was an American botanist, horticulturist and pioneer in agricultural science. He developed more than 800 strains and varieties of plants over his 55-year career. Burbank’s developments included those of fruits, flowers, grains, grasses, and vegetables. He developed (but did not create) a spineless cactus (useful for cattle-feed) and the plumcot.
