Euler was a famous Swiss physicist who was one of the most prominent mathematicians of his time, being the founder of the 'calculus of variations', the inventor of 'binary logarithms', and the third person in relatively modern times known to have advanced the theory of a hollow earth. Although he succeeded the scientists Halley and Mather, Euler was the first theorist to imagine the earth as w hollow globe devoid of additional "concentric spheres" as Symmes theorized, and theorized that the go-concavitic interior of the earth contained a single interior "sun" or luminescent orb at the exact center -- some believing this to be a focal-point of auroral or electro-magnetic energies -- which is now the most widely accepted of all 'Hollow Earth' theories today.
