Encyclopaedia Britannica is quite consistent in teaching Einstein's
idiocies:

http://www.encyclopedia.com/doc/1B1-372052.html
From: Britannica Concise Encyclopedia  |  Date: 2007
"Attempt to detect the velocity of the Earth with respect to ether, a
hypothetical medium in space formerly proposed to carry light waves.
It was first performed in Berlin in 1881 by A.A. Michelson and refined
in the U.S. in 1887 by Michelson and Edward W. Morley (1838-1923). The
procedure assumed that if the speed of light were constant with
respect to the ether, the motion of the Earth could be detected by
comparing the speed of light in the direction of the Earth's motion
and the speed of light at right angles to the Earth's motion. No
difference was found, and the result discredited the ether theory. As
a result, Albert Einstein proposed in 1905 that the speed of light is
a universal constant."

Compare with:

http://philsci-archive.pitt.edu/archive/00001743/02/Norton.pdf
John Norton: "Einstein regarded the Michelson-Morley experiment as
evidence for the principle of relativity, whereas later writers almost
universally use it as support for the light postulate of special
relativity......THE MICHELSON-MORLEY EXPERIMENT IS FULLY COMPATIBLE
WITH AN EMISSION THEORY OF LIGHT THAT CONTRADICTS THE LIGHT
POSTULATE."
