Wikipedia :

Ernst Florens Friedrich Chladni (UK: /ˈklædni/, US: /ˈklɑːdni/, German: [ɛʁnst ˈfloːʁɛns ˈfʁiːdʁɪç ˈkladniː]; 30 November 1756 – 3 April 1827) was a German physicist and musician. His most important work, for which he is sometimes labeled as the father of acoustics, included research on vibrating plates and the calculation of the speed of sound for different gases.^[1] He also undertook pioneering work in the study of meteorites and is regarded by some as the father of meteoritics.^[2

Van Dyke Parks comes to mind. He doesn't have a website, but his Wikipedia write-up will give you his outline.

Lately I've been devoted to abstract bands such 

Atrax Morgue and Zoviet France. They are of a distinctive styles, but both into dark ambient.

I was also fascinated by album of well known Jim O'Rourke "I'm Happy and I'm Singing and 1,2,3,4"
