KELLER's recognition symbol is the sea gull.

The gull stands like the pigeon in the Trinity picture as a symbol for philosophy, for the love towards wisdom and truth.

The owner of the company lives by the motto of his wise ancestors:

Son, you are free if you do not have to suck up to asses.
You are rich when you can tell them that.
You are wise if you do not have to tell them anymore.


It's the philosophy embodied in several articles that have made KELLER to the undisputed leader in Pressure Metrology. It is worthwhile to reflect about it.

 
 
Survival Marketing I

H. W. Keller about the origin of man, religion, the system.
 
Survival Marketing II

"Let everyone be a Greek - after his own fashion, but a Greek nonetheless." J. W. Goethe

"Rubbish!" says H. W. Keller. "Let everyone be a Socialist at heart, and a capitalist in his head."
