POTUS welcomes into its ranks 15 new members as of today. Since there was just one member before--me--that's a whole lot of new members.

I will tell you a bit about each one of them.

• Kathleen Dalton is the author of a biography of TR that is comprehensive, authoritative and a delight to read.

• Alonzo Hamby is the author of a biography of Harry Truman. Lon, as he is known to his friends, knows more about Truman than anybody (though he is too shy to say so himself).

• Joan Hoff is famous for her book about Richard Nixon, which ushered in a generation of fresh thinking about this much-maligned president.

• Jeffrey Kimball is well-known as a scholar on Vietnam; recently we had the pleasure of publishing one his pieces on HNN: Why It's Time to Use the"E" and"I" Words to Describe American Policies for 200 Years.

• Stanley Kutler is known chiefly for his fight to force the Nixon people to give up control of the Watergate tapes. But as readers of HNN know, he has scholarly observations to make about many subjects and he is always interesting.

• Allan Lichtman is known at the moment as a presidential historian at American University, but he may become more famous soon as a candidate for the US Senate in Maryland. We'll be watching.

• Timothy Naftali works for the Miller Center and recently published a dazzling history of counterterrorism (which was HNN's Book of the Month in July.

• Chester Pach is working on the University Press of Kansas history of the Ronald Reagan administration (earlier he did a book in the same series on Ike).

• James Pfiffner is a scholar of the modern presidency; you'll see him quoted just about everywhere.

• Mel Small did the Kansas book on Nixon, which was celebrated for its even-handedness.

• Gil Troy works in Canada, where he is a professor of history at McGill, but his area of study is the American presidency. Gil's latest book: Morning in America: How Ronald Reagan Invented the 1980s. (Disclosure: Gil is a member of HNN's Advisory Board.)

• Ted Widmer, a speech writer for Bill Clinton, now runs the CV Starr Center for the Study of the American Experience at Washington College and recently wrote a wonderful biography in the Schlesinger series on Martin Van Buren.

• Larry Wittner is one of the leading scholars of American nuclear history and the author of numerous essays for HNN including, most recently, Will We Still Remember Hiroshima After the Last Victims Die?. I first encountered him some 30 years ago. He was leaving Vassar just as I was beginning there as a student.

• Julian Zelizer, Professor of History, Boston University, is another scholar whose name you come across frequently in the media. He writes about presidents and Congress.

  And now--soon!--you'll be hearing from them all. (Pardon my boosterism. It's in my job description.)
