@tmkctm,
OK, since no one is even on the right track. Here is the answer:
Einstein is the one with wild hair and the most famous tongue in the world due to his famous picture to the press. Using google and wiki you can find out that he was born in 1879 and the year which he intreduced his "relative" theory was 1905.
so 1905+1879=3784
add digits until only one remains: 3+7+8+4=22
2+2=4
reflect on the ABC letters and you get
"The letter D".
This is only part 1 of the puzzle. in a few days i'll publish part 2.
