Ok, not a David Artiss, but another instance of my surname, thanks to Google Alerts.
A German company has concatenated “Artificial” and “Tissue” to “Artiss”, to form their company name.
The company, a biotechnological enterprise, was founded in 2000 under the name ATT. The name was changed to Artiss in 2001. The name has nothing to do with the founders of the company, who are Dr Haverich and Dr Heublein (Thanks to my girlfriend for performing the German to English translation!).
Not very exciting, but another spotting of my relatively rare surname.
