How Robert Caro Writes

CaroMost historians spend their careers jumping from topic to topic.  They finish a book on one subject and then move on to something different.  Perhaps they stay within their general area of expertise, but they seldom spend their entire life working on the same project.

That is why I am so fascinated by the career of writer Robert Caro.  After he won the 1974 Pulitzer Prize for The Power Brokera biography of New York developer Robert Moses, he spent the rest of his career writing about Lyndon B. Johnson.  He won a second Pulitzer in 2002 for Master of the Senatethe third book in his projected five-volume biography of Johnson.  He is currently at work on volume five.

Over at the Paris Review, Caro talks about his career, Lyndon Johnson, and how he writes.  Here is a taste:


How do you research a subject?


First you read the books on the subject, then you go to the big news­papers, and all the magazines—Newsweek, Life, Time, the New York Times, the Washington Post, the Washington Star, then you go to the newspapers from the little towns. If something appeared there, you want to see how it’s ­covered in the weekly newspaper.

Then the next thing you do is the documents. There’s the Lyndon Johnson papers, but also the papers of everyone else—Roosevelt, Truman, Eisenhower—whom he dealt with. Or for The Power Broker, Al Smith’s papers, the Herbert Lehman papers, the Harriman papers, the La Guardia papers. But to stick with Johnson, the LBJ Presidential Library is just massive. The last time I was there, they had forty-four million pieces of paper. These shelves go back, like, a hundred feet. And there are four floors of these red buckram boxes. His congressional papers run 144 linear feet. Which is 349 boxes. A  box can hold eight hundred pages. I was able to go through all of those, though it took a long, long time. This was when we were living in Texas for three years. Ina and I were spending five and a half days a week, typically, at the library. 

The presidency is different. There’s no hope of reading it all. You’d need several lifetimes. But you want to try to do as much as possible, because you never know what you will find. You have to rely on all of the cross-­referencing that the archivists have done. If it’s something really important, like a civil rights file, from 1964, 1965, or voting rights, you want to see everything. So I called for everything. But other­wise, you know you’re not seeing even a substantial percentage. You hope you’re seeing everything that really matters, but you always have this feeling, What’s in the rest?

So that’s the first three steps—the books, the newspapers and magazines, the documents. Then come the interviews. You try and find everybody who is alive who dealt with Johnson in any way in this period. Some people you interview over and over. There was this Johnson speechwriter, Horace Busby. I interviewed him twenty-two times. These were the formal interviews. We also had a lot of informal telephone chats. Once, he had a stroke. After he got better, he wrote Ina—he had a crush on Ina—“All I could think of when I went into the hospital was, ‘This will be hard on Robert, nobody else can tell him about the vice presidency.’ ” I came to love Buzz. But none of this is enough. You have to ask yourself, Are you making the reader see the scene? And that means, Can you see the scene? You look at so many books, and it seems like all the writer cares about is getting the facts in. But the facts alone aren’t enough.
