Der Universalgelehrte und der Bleistift – Der Gessner Bleistift

Der Gessner

Mit Mineralien die sich auf den Untergrund abreiben, und damit lesbar bleibt, wird schon seit früher Zeit geschrieben.
Aber im 16. Jahrhundert gab es bereits einen modernen Bleistift.

Das Prinzip eines Bleistift ist einfach. Ein Mineral, heutzutage meist ein Graphit-Ton-Gemisch, reibt sich auf den beschriebenen Untergrund ab. Dadurch ist die Schrift lesbar. Ein sehr einfaches Prinzip.
Komplizierter wird es wenn man sich näher damit beschäftigt aus welchem genauen Material, oder Materialgemisch, diese sogenannte Mine bestehen soll um am Besten zu schreiben.

Aber wirklich interessant wird es wenn man sich überlegt wie man diese Mine hält. Mit den Fingern. Klar. Mit dem Mund ginge auch noch, aber das Schreiben fällt schwer.  Nein, darum geht es natürlich nicht.
Man kann die Mine roh halten. Aber damit macht  man sich die Finger oft dreckig. Man kann die Mine natürlich auch in Holz packen. So sind heutzutage ja die meisten Bleistifte.

Ein wenig Historie muss sein

Conrad Gesner

In den Jahren 1516 bis 1565 lebte in Zürich ein Universalgelehrter namens Conrad Gessner. Ein Mann der in seiner Zeit sehr bekannt war, sogar Kaiser Ferdinand I. von Österreich persönlich. Er war unter anderem Arzt und auch Naturforscher. Und er schrieb Bücher. Über Tiere, Pflanzen und Minerale. Seine „Bibliotheca universalis“ umfasste 21 Bände. (Wobei Band 20 aus Geldmangel nicht erschien).
Und was Ihn außerdem besonders machte gegenüber Kollegen seiner Zeit war das Talent die Bilder zu seinen Büchern selber zu zeichnen.

Schließlich starb Conrad Gessner, auch Conrad Gesner geschrieben, an der Pest.

Aber was hat nun dieses Universalgenie mit einem Bleistift zu tun? Ganz einfach. Gessner zeichnete, und beschreibt, in einem seiner Bücher, genauer gesagt dem Werk „De Omni Rerum Fossilium Genere1, einen Bleistift. Und zwar einen der einem modernen Fallminienbleistift sehr ähnlich ist.
