Short Review: A good introduction to 13 theologians from the 20th century. These are academic and influential theologians but are often known for fairly theologically dense concepts. It can be a bit dry, but still helpful. The chapters have good context to the theological importance for each character so the chapters can be read independently and/or over time. (I read a chapter here and there for about 6 months.)
