In late 1914, Essanay succeeded in hiring Charlie Chaplin away from Mack Sennett's Keystone Studios, offering Chaplin a higher salary and his own production unit. Chaplin made 14 short comedies for Essanay in 1915, at both the Chicago and Niles studios, plus a cameo appearance in one of the Broncho Billy westerns. Chaplin's Essanays are more disciplined than the chaotic roughhouse of Chaplin's Keystones, with better story values and character development. The landmark film of the Chaplin series is "The Tramp" (1915), in which Chaplin's vagabond character finds work on a farm and is smitten with the farmer's daughter. Chaplin injected moments of drama and pathos unheard of in slapstick comedies (the tramp is felled by a gunshot wound, and then disappointed in romance). The film ends with the famous shot of the lonely tramp with his back to the camera, walking down the road dejectedly, and then squaring his shoulders optimistically and heading for his next adventure. Audiences responded to the humanity of Chaplin's character, and Chaplin continued to explore serious or sentimental themes within comic situations.
