Can you help us identify the person in this photograph? It contains at least two clues. The one legible book title in the stack behind him is The Analysis of Linear Circuits by Charles M. Close. This may indicate he was a member of the electrical engineering faculty. The second clue is his hair style, which looks mid-1970s to mid-1980s.

I taught circuit theory as a graduate student under Professor Charles Close. He was a perfectionist in his writings and teaching methods and I imitated him as best I could. I consider him to be one of the great mentors in my professional career.
The photo is of Charles Close
This is Charles M. Close himself!
I still have the book, as well as a similar hair style!
I confirm that this is Dr. Close. He was my advisor my senior year.

I still have this book as well. Professor Charles Close was a major factor in my graduation in 1973 as an Electrical Engineer. He was a wonderful person and I had a long career as a radar engineer and physics teacher thanks to him. This is a picture of him, although I do not remember the long hair in the summer of '73.
