Geschichte der Design Patterns

Each pattern is a tree-part rule, which expresses a relation between a certain context, a problem, and a solution.
The Timeless Way of Building, Alexander 1979

Each pattern describes a problem which occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing the same way twice.
A Pattern Language - Towns, Buildings, Construction, Alexander 1977

A pattern lives when it allows its own inner forces to resolve themselves.
The Timeless Way of Building, Alexander 1979
