My Job: Mark Horowitz, from Broadway to the Beltway

Mark Horowitz in the Music Division works with some of the biggest names in musical theater.

Describe your work at the Library.

I’m a senior specialist in the Music Division’s acquisitions and processing section, where my specialty is American musical theater. I acquire collections for the Library — these have included the papers of Howard Ashman, Adam Guettel, Marvin Hamlisch, Jonathan Larson, Hal Prince, Jeanine Tesori and a promised bequest from Stephen Sondheim.

I process special collections — sorting, organizing, identifying, foldering, labeling and writing finding aids. I provide reference. And I get to do special projects, such as co-producing concerts and exhibits and conducting interviews for the Library’s website — including interviews with Sondheim, Burt Bacharach and Randy Newman.

What are some of your standout projects?

Producing a 70th birthday celebration concert for Sondheim. Our cast included Nathan Lane, Audra McDonald, Marin Mazzie and Brian Stokes Mitchell. It included a newly orchestrated concert version of his “The Frogs,” which was then recorded for the first time and led to an expanded version of the show premiering on Broadway. That concert included a segment of Sondheim’s “songs he wish he’d written,” the complete list of which was then published in the New York Times and led to a series of Barbara Cook “Mostly Sondheim” concerts and recordings.

In 2018, I received the Kluge fellowship reserved for a Library staff member. My project allowed me for one year to seek out, read, review, select and transcribe correspondence from and to the lyricist, librettist and producer Oscar Hammerstein II. Among the shows Hammerstein wrote were “Show Boat,” “Oklahoma!,” “Carousel,” “South Pacific” and “The King and I.” His correspondence represents a who’s who of show business, but he was also deeply involved in social issues, including working with the NAACP. I ended up transcribing over 4,500 letters. The plan is that these transcripts, accompanied by scans of at least some of the originals, will become a Library website. I believe these letters will be a revelation to many and prove a vast source for research.

What have been your most memorable experiences at the Library?

Making Stephen Sondheim cry when I showed him Gershwin’s manuscript for “Porgy and Bess.” Doing a show-and-tell for Angela Lansbury, during which she sang “Beauty and the Beast” for me, first as Ashman and Alan Menken had performed it for her (up-tempo), then the way she insisted on singing it (as a ballad).

What are your favorite collection items?

There are hundreds, but the first that comes to mind: Oscar Hammerstein’s lyric sketches for “My Favorite Things” (“Riding down hill on my big brother’s bike/These are a few of the things that I like”) and “Do-Re-Mi,” where for several pages he gets stuck on the line “Sew — a thing you do with wheat.” Larson’s lyric sketches for “Seasons of Love,” where you see him do the math that calculates there are 525,600 minutes in a year. A letter from George Bernard Shaw to a 19-year-old Jascha Heifetz, cautioning him to play something badly every night instead of saying his prayers so as not to provoke a jealous god.
