Among the long established and successful business enterprises of New Hamburg must be ranked that of Mr. E. R. Beger, carriage manufacturer. It is 38 years since Mr. Beger located as a blacksmith on the property where now stands a substantial 3 story brick factory. The main building is about 60 feet square, exclusive of the 30 x 40 foot blacksmith shop which is detached. The firm turns out about 100 vehicles of one kind and another, annually. These consist of buggies, stanhopes, traps, runabouts, cutters and sleighs and it is safe to say are not surpassed in point of beauty and durability by the output of any other Canadian firm. A thorough mastery of his business combined with a strict integrity and a disposition to give every man a square deal, constitute the corner stone upon which Mr. Beger has so well builded numbers among his patrons, not only in Waterloo County, but also in the surrounding counties and even farther afield. Indeed, so flattering has been the reception of his carriages that Mr. Beger intends to invade the West and will shortly open an agency out there. Actively associated with him is his son, Mr. R. E. Beger, who is of great assistance to his father in energetically pushins; forward a growing business. Mr. Beger has always taken an interest in public affairs and spared neither his time nor his money to advance the interests of New Hamburg. He had the honor of filling the Reeve's chair for two years, but prior to that had served at one time and another some 25 years in the Council.
