His insistence and perseverance have saved TeX Live from many disasters and bugs. Although I have been in contact with Staszek over the TeX Live mailing lists since some years, I met him in person for the first time on my first ever BachoTeX, the EuroBachoTeX 2007. His friendliness, openness to all new things, his inquisitiveness, all took a great place in my heart."
