Thank you for leaving a comment. I confirm that in this article I've covered two rather complex topics: Bode and Nyquist were two geniuses who left us some very important works. Both were Americans. Hendrik Wade Bode was born in 1905 and died in 1982, while Nyquist was born in 1889 and died in 1976. Nyquist was born in Sweden and then emigrated to the United States. Nyquist is also known for his sampling theorem. !DIY
