TITLE: What is the value of this continued fraction?
QUESTION [6 upvotes]: I am curious about the value of the continued fraction $$1+\cfrac{1}{2+\cfrac{1}{3+\cfrac{1}{4+\cfrac{1}{5+\cfrac{1}{6+\dots}}}}}.$$ 

Can we evaluate it ?
Is it a nice value ?  

Clearly it should be a transcendental number. But I have no idea about calculate it.
