Gilda Radner, Jane Curtin —
In 1975, "Saturday Night Live" debuted and introduced viewers to history-making comedians like Gilda Radner, left, and Jane Curtin, who were part of the original "SNL" cast. The duo put in place some of the most iconic sketches to date, from the Coneheads to Baba Wawa. Post-"SNL," both were poised for screen success, but Radner's career was cut short by her death in 1986. Curtin went on to star in sitcoms like "Kate & Allie" and "3rd Rock from the Sun."
