46 years after this article, Alan Konheim, the founding Chair of the UCSB’s Computer Science Department wrote an article on Horst Feistel in the Journal of Cryptographic Engineering of which I am the Editor-in-Chief.

Alan Konheim was my professor when I was a graduate student at UCSB. Alan died in 2019, may his soul rest in peace.
The first sentence of the JCEN article’s Acknowledgement section writes:
“I am particularly grateful for the assistance given by my former UCSB student and later colleague Çetin Kaya Koç, editor-in-chief of the Journal of Cryptographic Engineering, who invited the submission of this paper,”
