I just heard the shocking news that Patrick Tisseghem, co-founder, managing director of U2U and Microsoft SharePoint MVP, has passed away last week. This is a great loss for the SharePoint community. The U2U website has this to say:

It is with deepest regret that we have to announce the death of Patrick Tisseghem, co-founder of U2U. Patrick suddenly passed away on Wednesday 3 September 2008 around 18 hours in Gothenburg Sweden due to a heart failure. Our sympathy and thoughts go out to his wife Linda, their daughters Anahi and Laura, and to his family. We are all deeply saddened by this tragic loss. We remember him as caring father as well as a driven and warm hearted colleague and friend. We miss you Patrick.

The last time I spoke to Patrick was a few months ago at the Dutch Microsoft DevDays 2008 in Amsterdam. After one of his sessions he helped me out with some SharePoint custom security trimmer problems I had.

I think he was a great guy and I always liked attending his presentations. Especially the funny, sarcastic, remarks used to make about SharePoint. My deepest condolences to his wife and daughters. Goodbye and thank you, Patrick!
