The three Samwer brothers are well known in internet entrepreneurs in Germany. Now they make headlines with a high profile investment in social networking king-pin Facebook.

The Samwer brothers founded successfully in the past the Alando auction platform they sold to eBay and the Jamba ringtone company which they sold to Verisign.

There is no official statement on the size of the investment. The WSJ thinks it’s between $10 and $15 million. A while back Microsoft invested $240 million in Facebook.

Along with the Facebook investment the Samwer brothers are supposed to help launch Facebook in Europe.
