Rachel Shukert tracks the rise of Jewish characters in Mad Men as a portrait of cultural assimilation:
[I]t wasn’t until last season that we got Michael Ginsburg, the whiz-kid copywriter. With his thick “regional” accent, Yiddish-accented Old Country father who likes farmers’ cheese and has a dimly remembered tragic early childhood in a concentration camp, Ginsburg is the first Jewish character on Mad Men who isn’t, on some level, trying to hide it. Roger Sterling, ever the gentleman, may have taken it upon himself last season to make sure their client Mohawk Airlines could deal with “working with a Jew,” but the times, they are a changin.’
