Roger Herz-Fischler is a retired professor of mathematics. After years
of doing research in theoretical probability he became interested
in the sociology of mathematical myths, in particular of the golden number.
His research, always based on original source material,
led to his books:

*A Mathematical History of Division in Extreme and Mean Ratio*,
republished as *A Mathematical History of the Golden Number*

*The Shape of the Great Pyramid*

* Adolph Zeising / (1810-1876) / The Life and Work of a German Intellectual*

as well as to many articles.

In addition to his research publications, Roger Herz-Fischler
is interested in pedagogy and has published four textbooks, including *A Guide to Matlab*; see below.

"Theorem XIV** of the First
`Supplement' to Euclid's
*Elements*" *Archives internationales d'histoire
des sciences* 38 (1988), no. 120, pp. 3-66 [I consider this as my best work].

"De quand date le premier rapprochement entre la suite de Fibonacci et la division en extrêeme et moyenne raison?" (with L. Curchin).

"Proportions in the Architecture Curriculum" A link to the article in HTML format. The article in PDF format. N.B. In the PDF version Figure 21, "Garches" is labelled 21 and Figure 22 "Stuttgart" is missing.

"Le Nombre d'Or en France de 1896 à 1927" The article itself. Notes for the article.

"How to Find the 'Golden
Number' Without Really Trying"
[This is suggested reading for anyone who is analysing literature, music or anything involving counts; for
continuous measurements see the chapter on philosophy in* The Shape of the Great Pyramid*.]

"The Home of Golden Numberism"

"On the Application of the Golden Ratio in the Visual Arts"

"Seurat and the Golden Number"

Several of my articles deal entirely or in part with Le Corbusier:

Case studies 10, 11 and 12 of "Proportions in the Architecture Curriculum" discuss, with mathematical details, Le Corbusier's methods. Figures 20 -- 28 may be consulted in connection with the next two articles. For a clearer copy of the preliminary sketch (Figure 21) for Garches, see below.

"The Early of Relationship of Le Corbusier to the 'Golden Number' "

The printed version of "Le Corbusier's 'Regulating Lines' for the Villa at Garches (1927)
and Other Early Architectural Works" was a much shortened version (16 footnotes) of the original (40
footnotes) version. Following several exchanges with Jef7rey Hildner (see his *Garches 1234*, special
edition, Boston:
The Architect Painter Press, 2009, for many drawings,
photographs and his analysis of Garches) I have decided to present my original version (typed in Paris in
early 1983; the lines and streaks represent "cut and paste" in the pre-word processor sense). See
"Proportions in the
Architecture Curriculum" for the diagrams referred to.

The article "Le Nombre d'Or en France" discusses Le Corbusier's relationship to the painters Gris and Severini.
