How about giving him a German-themed gift basket? You can fill the basket with items such as German chocolates, beer mugs, a German cookbook, a German language phrasebook or a book about the history of Germany. You can also consider gifting him a German-inspired cooking class or a guided tour of German cultural sites in your area. Additionally, a traditional German-style shirt or hat would be a great personal touch to the gift.
Or you can get him a star map with the date when he was born.
