The Individualist Anarchist

 There is no doubt that Max Stirner is the philosophical father of individualist anarchism. He is a subjective idealist to a large degree, but he is likely more of a subjective materialist. He cannot be a subjective idealist per se like Berkeley because the latter believes in God and denies the existence of objective reality. 

Stirner is an individualistic atheist and materialist. He is not a solipsist for the Unique interacts and enjoys his property, which is his internal consciousness, others outside of himself, and his personal use and enjoyent of the external world itself.

Stirner is a subjective individualist anarchist whereas I am an objective individualist anarchist more than a subjective individualist anarchist.
