Francis Bacon noticed in 1620 that the outlines of the continents fit together like a jigsaw puzzle, but did not suggest a theory of why.
Benjamin Franklin wrote in 1780 that the crust of the Earth must be a shell that can break and shift by movements of a fluid below
The proper theory of continental drift was suggested by Alfred Wegener in the early 20th century. He published a book "The origin of the continents and oceans" proposing the existence of a supercontinent he called Pangaea about 250 million years ago.
He was unable to explain a driving mechanism, which is one of the reasons why his theory was at first rejected by the scientific community.
Alfred Wegener
German scientist Alfred Wegener (1880-1930) first proposed the theory of continental drift in 1912, but it was not widely accepted until the 1950s.
The idea of continental drift was first proposed by Alfred Wegener in 1912. Wegener's theory suggested that the continents were once joined together in a single landmass called Pangaea and had drifted apart over time.
The German scientist, Alfred Wegener first proposed the continental drift theory.
hello
Supercontinent was first proposed in 1912 by the German meteorologist Alfred Wegener as a part of his theory of continental drift.
Alfred Wegener, a German meteorologist, proposed the first formal theory of continental drift in 1912. He suggested that the continents were once joined together in a single landmass called Pangaea, which later broke apart and drifted to their current positions.

A German scientist Alfred Wegener first proposed the idea of Continental Drift.
The theory of continental drift and plate tectonics
The main problem with Wegners theory of continental drift was that at the time he proposed it he had no real proof.
That would be Alfred Wegener.yah! it's true ALFRED L. WEGENER [1880-1930] who first proposed the CONTINENTAL DRIFT IN 1912. obejerojamjam@yahoo.com :))
