Mad Men

Bertram "Bert" Cooper (Robert Morse): The somewhat eccentric senior partner at Sterling Cooper. He leaves the day-to-day running of the firm to Sterling and Draper, but is keenly aware of the firm's operations. Like many of his executives, Bertram is a Republican. He is fascinated by Japanese culture, requiring everybody including clients and his sister (a shareholder) to remove their shoes before walking into his office (which is decorated with Japanese art). He is a fan of the writings of Ayn Rand and implies he knows her personally. Among his eccentricities, Bert frequently walks through the offices in his socks and intensely dislikes gum and smoking (an oddity for the time, especially considering that Lucky Strike cigarettes is a major client). He owns a ranch in Montana and is a widower with no children.
