CU-麻豆影院 historian Tom Zeiler introduced students to "America through baseball" nearly 15 years ago. They clamored to get in then, and still do.

罢辞听Zach Weinstein, Tom Zeiler鈥檚 arrival in his Jewish Studies seminar one day last winter seemed a favorable sign, especially after Zeiler sat next to him.

Weinstein (Hist, Phil鈥16) had always wanted to take 鈥淎merica through Baseball,鈥 the hugely popular course that Zeiler, a CU-麻豆影院 history professor, pioneered on campus. But the timing had never worked out.

It suddenly seemed it might: Zeiler, who was observing the seminar, revealed he would offer the baseball course as an on-campus lecture for the first time in years and in its biggest incarnation yet, 250 students.

鈥淚鈥檓 lucky that I鈥檓 still here,鈥 says Weinstein, 25, who started at CU in 2007, left to work, then came back.

Zeiler developed 鈥淎merica through Baseball鈥 in 2000, while researching a book about baseball and cultural diplomacy. He thought the course might broaden undergraduate appetites for meaty topics in American history 鈥 urbanization, nationalism, labor strife, the Roaring 鈥20s, race relations, the Cold War and globalization.

It proved a hit.

鈥淧eople from all different majors want to take it,鈥 says Weinstein.

Over time, Zeiler has offered the course as a lecture, a seminar and, most often lately, a full-credit online course. When he taught it in baseball-crazed Japan during a Fulbright fellowship, the president of Japan Women鈥檚 University dropped in, he says. So did Bobby Valentine, the former New York Mets manager, then working in Japan.

Eventually, CU history instructor聽Martin Babicz聽(PhDHist鈥09) also began offering the course, as a freshman seminar.

Whatever the format, 鈥淎merica through Baseball鈥 is not about box scores.

鈥淭his is American society and history,鈥 Zeiler, an expert in U.S. diplomatic history and director of the Program on International Affairs, tells students. 鈥淵ou don鈥檛 come in here because you have a baseball mitt.鈥

For the professors, baseball offers both a framework and a bounty of personalities for dramatizing and personalizing American history.

The careers of 19th-century player-businessmen Albert Spalding and John Montgomery Ward lead to discussion of baseball鈥檚 growth as a complex capitalist enterprise and the rise of labor unions, for example. Babe Ruth, larger than life, personifies the Roaring 鈥20s. And Jackie Robinson鈥檚 1947 debut with the Brooklyn Dodgers as Major League Baseball鈥檚 first black player prompts examination of racial attitudes.

In the same way, the Cincinnati Reds鈥 decision to change their name, briefly, to the Redlegs illustrates the depth of anti-communist hysteria in the 1950s. And the relocation to California of the Brooklyn Dodgers and New York Giants after World War II helps bring to life western migration and the rise of the sun belt.

When Zeiler first proposed the course, some colleagues questioned its academic merit, he says. But like baseball-minded professors before and after him, he prevailed. San Francisco State, Kansas State, the University of Iowa, the University of Chicago, Tufts and Harvard, among others, all offer or have offered baseball-related courses.

Interest in baseball as a vehicle for teaching American history is now so widespread that publisher Rowman & Littlefield has hired Zeiler and Babicz to write a textbook tentatively titled National Pastime: United States History through Baseball.

CU students of all kinds take the course 鈥 baseball aficionados and novices, accounting majors and engineers, the simply curious and the intensely motivated. Zeiler says at least half the students are women. Babicz finds that many students perform better than their counterparts in his conventional American history survey.

For Weinstein, the main appeal is the unusual approach to the material and a sense of its potential, he says, to 鈥渃onfront me with something I don鈥檛 normally think about.鈥

The course works its influence beyond the classroom, too.聽Lisa Mercadante聽(IntlAf鈥09) couldn鈥檛 fit it into her schedule 鈥 but its existence alerted her to Zeiler, who advised her honors thesis about MLB鈥檚 effect on the Dominican Republic, a key source of players today.

Now a graduate student and teacher of English as a second language, Mercadante is exploring roles with professional baseball teams as a mentor for foreign players.

鈥淎merica through Baseball,鈥 like sport itself, brings people together.聽Jesse Lopez聽(Acct鈥15) took the course online, visiting his father nightly to share the experience. The former Marine, 30, says it deepened his understanding of racism in America.

鈥淚t was incredible to read things and then have my father explain what he was going through at that time or his understanding of it,鈥 says Lopez.

In the fall, Zeiler anticipates another full house for 鈥淎merica through Baseball.鈥

鈥淓veryone in the class is eligible for an A,鈥 he jokes. 鈥淚t just doesn鈥檛 work out that way.鈥
