Once a biographer, always a biographer. A few years ago I wrote the first and only biography of Millicent Fenwick aptly called “Millicent Fenwick: Her Way.” Fenwick’s life spanned the twentieth century from 1910 to 1992. Although she is no longer with us, the serendipitous connections are everywhere. Lucky for me (and the reader), I’m working on another biography, “Leading Justice: The Life of Nicholas Katzenbach,” so you will get a double dose of the many intersections I discover between my subjects and the present. And if you don’t know who Fenwick or Katzenbach are, you soon will.
