A notable omission is reference to French inventor Claude Chappe, who in 1792 demonstrated a free space optical communication system.
It was the first practical telecommunications system of the industrial age, that eventually spanned all of France, until replaced with electric telegraph in 1850s.

I noticed right away that the J.H. Bunnell & Co. image of "THE MORSE TELEGRAPH ALPHABET" is markedly different from standard Morse code. The article does not mention anything about the evolution of Morse code itself.
