Which letters in the alphabet are used most often?

The inventor of Morse code, Samuel Morse (1791-1872), needed to know this so that he could give the simplest codes to the most frequently used letters. He did it simply by counting the number of letters in sets of printers' type. The figures he came up with were:

12,000 E 2,500 F
9,000 T 2,000 W, Y
8,000 A, I, N, O, S 
1,700 G, P
6,400 H 1,600 B
6,200 R 1,200 V 
4,400 D 800 K
4,000 L 500 Q
3,400 U 400 J, X
3,000 C, M 200 Z

Happy Birthday Samuel Morse 4/27/1791

Samuel Morse inventor of the Morse Code
April 27, 1791

Morse code is a method of transmitting text information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment. The International Morse Code encodes the ISO basic Latin alphabet, some extra Latin letters, the Arabic numerals and a small set of punctuation and procedural signals as standardized sequences of short and long signals called "dots" and "dashes",or "dits" and "dahs". Because many non-English natural languages use more than the 26 Roman letters, extensions to the Morse alphabet exist for those languages.
