Once upon a time, he was to have played the lead roll in a film. However, before he could conquer the silver screen, sketches of this droll cat started quite some excitement in the world of print.
A cat-lover who was astounded at the similarity between the drawn cat and her own domestic tiger, insisting "That's my Jacob!" thus gave him his name, as well as bringing together Jacob's two "fathers", the artist Sven Hartmann and the writer Thomas Haertner, who died in 2010.

For around forty years, the team of Hartmann and Haertner have worked on and with Jacob, spreading his stories in picture and text in five languages, in the form of books, calendars (F.W.Heye Verlag ), and in magazines.
In his uniquely light-hearted and ironic manner, Jacob comments upon all the daily events and experiences which happen to him and his chum. The cartoons and comments bring a smile and often a hearty laugh. The observer becomes aware of and is amused by his own shortcomings and little weaknesses as pointed out by the sympathetic and lively cat. In this way, Jacob provides his readers with a humourous little philosophical "poke" along their way.
And even without words, Jacob is very appealing - just look at him gracing T-shirts, mugs, umbrellas and all those other goodies in our shop! His mischievous smile, with head resting on velvety paws - you can't help wanting to take him into your arms and give him a good cuddle! Which is no problem - he's available as a stuffed toy (made in Japan, please have a look to Cosmo Merchandising Co., Ltd ) in all possible variations - even one which goes "meow! meow!" These and other Jacob products can be found in Jacob's Shop
