ESCANABANS SUCCESSFUL ON STAGE AND SCREEN
It was a Hard Road To Travel, but Lottie Mineau, Walter Long, Arthur White and Agnes Casey Made Good
Hollywood and Broadway! There is magic in these words.Whether you have been there or not, mere mention of Hollywood conjures in the mind a panoramic view of the celebrated movie colony - its exotic atmosphere, its conglomeration of people from many lands, castles of Spain in which famous cinema stars dwell, the “lot” bustling with activity, directors barking through megaphones, and - its front page scandals.This City of Make Believe is the Promised land of those who seek fame and fortune.It is a paradise for those who triumph, but a hell for those unfortunates who fail. And Broadway.It had its footlights which brighten the faces of stage successes, its Earl Carroll baths, millionaire stage Johnnies, night clubs and Prohibition padlocks.Broadway represents to the aspiring actor the attainment of a life long desire. Four Escanabans Successful Over the hard and rocky road to Hollywood and Broadway, four former Escanaba residents have traveled, and overcoming the numerous obstacles that have faced them, have achieved success.They are; Charlotte Mineau, Walter Long, Agnes Marie Casey and Arthur Courtney White. Starting with the old Essanay company Chicago back in the days when the movie industry was in its infancy, Miss Charlotte Mineau know to her many Escanaba friends better as Lottie, has had a variety of experience in screendom that is probably unequaled.She has run the gamut of slapstick comedy parts with Charles Chaplin and Mack Sennett to dramatic character roles with Mary Pickford. She was born in Escanaba, the daughter of Mr and Mrs Adolph Mineau.Her father was drowned only two months after her birth while making a daring trip with a rowboat of the Chandler Falls in Escanaba river.Her mother is now living Burlington, Vermont.Lottie attended school here and later wen to Green Bay Business College following which she was engaged in stenographic work here for a short time before going to Chicago. Pictures Shown here Miss Mineau’s pictures have appeared at local theaters often.While with Essanay, she played leads in the famous George Ade fables and later co-featured with Wallace Beery in the ‘Swedie” series.After going to Hollywood, she became associated with that peerless screen comedian, Charles Chaplin, with whom she remained for two years.Joining the Mack Sennett studio she appeared for several years in leading roles with Charles Murray, Ford Sterling, Harry Langdon and other comedy stars.She also starred in nine consecutive comedies produced at the Hal Road studio. In free lancing, Miss Mineau’s has support such noted film stars as Mary Milnes Minter, Mabel Normand, Owen Moore, Laurette Taylor and Mary Pickford. Beauty was Hindrance Being too attractive almost caused her one of the greatest opportunities of her screen career.When Mary Pickford was casting her production, “Scraps”, she and her director, William Beaudine, had great difficulty in finding the proper to person to essay the role of “Mrs. Grimes”, a slovenly and ill-tempered character. Scores of applicants for the part were considered but none came up to the requirements until Miss Mineau was sent for.In this artist, the Pickford studio officials believed, they would have an actress of ability and understanding, and it was not until the comely Miss Mineau called at the studio looking like the proverbial “million dollars” that any doubt entered the minds of Miss Pickford and her director. “You won’t do,” the director flatly informed Miss Mineau.“You’re too good looking.” “What’s the part?” asked the actress. The director shoved a sheaf of manuscript at her and promptly forgot her. Two days later, the character - a slatternly, careworn farm woman - walked into the directors office. “Do I get the part?” she inquired in a tired drawl. Suffice it to say Miss Mineau got the coveted role.The transformation of the smartly clad woman into the disreputable rags and makeup to “Mrs. Grimes” turned the trick. Recently, Miss Mineau suffered injuries in a peculiar accident.A cab backed into a motorcycle standing at the curb and overturned it against her leg.She sued the cab company for $10,200 damages, but the case was later settled out of court. It is several years since Miss Mineau has visited the old home town, but friends of the family who have called on her on their visits to Hollywood report that she is always interested to receive news of Escanaba.She resides at 803 North St. Andrews Place, Los Angeles, Cal.
