I haven't given it too much thought but my initial reaction was to list the names and see what came to mind whilst considering they are part of a code challenge --
Samuel -- Samuel Morse -- Morse code ?
Louis -- ?
Ludwik -- ?
Tim -- Tim Berners-Lee ?
Perhaps we need to convert each of the characters in the given message to Morse code and lay out the result in strict time sequence. The length of a "dot" is one time unit. The length of one "dash" is three time units. The length between parts of the same character is one time unit. The length between characters is three time units. The length between words is seven time units.
The first two "words" are "IN AAAAIAN ". Let the "#" character represent a unit of time. Let a plus character, "+", represent the audio tone generated by an oscillator that is being keyed to communicate the above two words and a space character, " ", represent the absence of the audio tone. I now see --

+ + +++ + + +++ + +++ + +++ + +++ + + + +++ +++ +
Hmm . . . I need to use squared paper, where each square is one time unit and a filled in square indicates the tone from the audio oscillator.
Sudden thought after looking at the preview of this post -- Braille.
Wikipedia tells me that Braille was created by the Frenchman, Louis Braille.
So convert characters seen to Morse code on a strict time scale and then lookup the result as Braille.
Who is Ludwik? It's certainly not Ludwig van Beethoven, note the different spelling . . . Calling all Kitizens
