Lightning Fastener Co. Ltd. was a zipper manufacturer located on Niagara Street in St. Catharines. It was founded by Gideon Sundback, the inventor of the modern fastener. Sundback was born in Sweden, but settled in the United States in 1905. It was here that he designed and patented a “separable fastener” in 1913. Although he lived in Hoboken, New Jersey, he decided to establish a manufacturing facility for his invention in Canada, choosing St. Catharines over other locations such as Fort Erie and Hamilton. At the height of its success, the company employed more than 500 people and produced more than 50 million zippers annually. Over time, the company had difficulty remaining competitive and was forced to close in 1981.

Construction on the Thorold tunnel began in 1965 and was completed in 1967. It was designed by H. G. Acres & Company Ltd. and built by Pitts-Atlas, a joint venture of C.A. Pitts, General Contractor Ltd., and Atlas Construction Company Ltd. The tunnel replaced two lift bridges (Bridge 9 at Ontario Paper Co. and Bridge 7) that carried traffic over the Welland Canal. The majority of the construction occurred during the winter months, when the canal was closed to shipping. The water was drained and concrete sections shaped liked tubes were poured, creating the tunnel. During the summer months, the end sections of the tunnel were constructed so that shipping could continue uninterrupted. The 24 million dollar project was financed jointly by the Department of Highways and the St. Lawrence Seaway Authority. The tunnel was officially opened on September 18, 1968.

The Woodruff Family Collection: From the time the Woodruff Family came to Canada from the United States in 1795, they took an active role in the forming of their communities both in a civic and social manner. This is evident through the documents contained in this collection. The Woodruffs played an active role in the battles fought in Upper Canada and they were an integral part of the Village of St. Davids. They were educated, business-minded and socially engaged. They accumulated much of their fortune through land dealings. Much of this collection focuses on Samuel DeVeaux Woodruff who was principally a businessman. His dedication to his work is shown through his numerous undertakings. He made his mark on the Niagara Peninsula through his work on the railways, roads, marsh land revisions, canals and the paper industry. He was also involved with the founding of the Long Point Company and he took control of building DeVeaux Hall down to the last detail. His offspring inherited his work ethic and his business acumen. The people who married into the Woodruff Family also possessed key social, political and business ties. Anne and Margaret Clement were from a staunch Loyalist background. Samuel Zimmerman was instrumental to the founding of Niagara Falls and Judge Samuel DeVeaux left behind a legacy for poor and homeless boys in Niagara Falls, New York. The Woodruff Family undoubtedly left a mark on the Niagara Peninsula. This collection brings to light many endeavours of the family and their varied contributions.
