The Theorem in brief

In the world of art I always moved alone. My work grows on a rational basis, but has nothing in common with the so-called "Zurich school of concrete art". The more years and realizations, the clearer it became that all my doing unfolds in a system. After a long trial and error, in the year 2000 I succeeded in clearly grasping this process in the so-called Granwehr's Theorem. It is based on an operation with the quotient series of all ones: 1, 11, 111, 111 and so on. Thanks to the theorem, a powerful sequence of pencil drawings has been created. Each theme contains 32 sheets and unfolds in four eight-part series. Some titles: "For a reason", "Is as it were like", "Parts allotted", "Around the zero point", "How just something". Until the end of 2012 Theorem includes 500 optical expressions, that is 16 000 drawings. Now take a look at the expression "Flächenfolgen" from 2012 as a representative of the entire oeuvre.

Theorem: Preliminary work 1987 - 1998

In 1998 Florin Granwehr created the basis for the graphic work of the next 20 years with the Theorem. These drawings on graph paper are preliminary works. Pencil drawings A4 on graph paper

1987: XYZ (98 drawings)
1987: Numbers masterly (159 drawings)
1991: Number mirror (94 drawings)
1997: Eightness (432 drawings)
1997: Three at three (478 drawings)

Granwehr's theorem 2000

The 2000 volume contains the theoretical derivation of Granwehr's theorem and 500 drawings in which the mathematical considerations take aesthetic form.

14 drawings A4, pencil on paper with the theoretical derivation of the theorem as a draft and as a final drawing.

Introductory text to the theorem 500 drawings A4, pencil on paper, each as a draft and as a final drawing. In total 1000 drawings.

Repetitorium 1976 - 2001

In 2001 Florin Granwehr transfers older, large-format ink drawings with pencil onto A4 paper. One can only speculate about the reason. Possibly he wanted to investigate how far the theorem can be transferred to earlier works.

298 drawings A4, pencil on paper All final drawings, no drafts

Applications Theorem 2001 - 2002

Early drawings in application of Granwehr's theorem in A4 format. From 2002 the artist works consistently in series of 32, but not yet in these earlier drawings of 2001 and 2002. Most of the drawings exist as drafts and as final drawings.

2001: "In and of itself" (100 drawings)
2001_"Fourfold variety" (100 drawings)
2001: "Completely" (50 drawings)
2002: "Apriori" (224 drawings)
2002: "One to one" (52 drawings (only final drawings))
2002 "Grundverschieden" (480 drawings)
2002 "Schwerpunkleicht" (192 drawings)

Theorem 2002 - 2018: Introduction

In Theorem Florin Granwehr works throughout and consistently with pencil on A4 paper. The work consists exclusively of 32 series of drawings that always follow an order pattern. Here is an example of such a series. In total, the estate comprises over 600 such series. Here is a short introductory text by Astrid Näff on the work of Florin Granwehr with a section on the theorem.

Theorem 2002 - 2018: design drawings

Florin Granwehr called the theorem "work of silence" and he worked on it for 20 years undisturbed, but also unnoticed. Starting from basic mathematical studies in 1998 and the will to give an aesthetic form to these observations by means of geometry, almost 40,000 drawings were created. Looking through the works, it becomes clear that Florin Granwehr's Theorem is not about order, however, but about the search for the mystery inherent in every order. This ambiguity makes the Theorem an artistic work to be discovered.

More than 19,000 design drawings pencil on paper A4 in over 600 32 series.

Theorem 2002 - 2018: final artwork

More than 19,000 final drawings pencil on A4 paper in over 600 32 series.
