Why 'Cognitor' for our website and our emails?

Cognitor is derived from the Latin verb cognoscere. This multilayered verb means in particular: knowing, recognizing, perceiving, experiencing, exploring, investigating, representing in court.
The cognitor thus is a knowledgeable person, a cognitive person etc. ... and a representative in court.
In our work as lawyers, we always strive to be a cognitor. With cognitor in our e-mail and website, we continue the tradition of Dr. Gautschi, who founded our law firm on October 1,1932. He had already registered cognitor as a short address for telegrams sent to the firm. The incorporation of the word cognitor into the e-mail and website address thus takes us back to the roots of our firm.
