The definitive biography of a distinguished public servant, who as US Secretary of Labor, Secretary of the Treasury, and Secretary of State, was pivotal in steering the great powers toward the end of the Cold War. Deftly solving critical but intractable national and global problems was the leitmotif of George Pratt Shultz's life. No one at the highest levels of the United States government did it better or with greater consequence in the last half of the 20th century, often against withering resistance. His quiet, effective leadership altered the arc of history. While political, social, and cultural dynamics have changed profoundly since Shultz served at the commanding heights of American power in the 1970s and 1980s, his legacy and the lessons of his career have even greater meaning now that the Shultz brand of conservatism has been almost erased in the modern Republican Party. This book, from longtime New York Times Washington reporter Philip Taubman, restores the modest Shultz to his central place in American history. Taubman reveals Shultz's gift for forging relationships with people and then harnessing the rapport to address national and international challenges, under his motto "trust is the coin of the realm"-as well as his difficulty standing up for his principles, motivated by a powerful sense of loyalty that often trapped him in inaction. Based on exclusive access to Shultz's personal papers, housed in a sealed archive at the Hoover Institution, In the Nation's Service offers a remarkable insider account of the behind-the-scenes struggles of the statesman who played a pivotal role in unwinding the Cold War.
