Records of the Rayovac corporation, mainly from the 1920s to the 1990s, a battery company founded as the French Battery and Carbon Company in 1906, with Rayovac currently a subsidiary of Spectrum Brands. The collection contains advertising materials, product development drawings, financial statements and audits, employee newsletters and records of a women's employee club, a small amount of correspondence and directors meeting minutes, some legal documents, and various compiled histories of the company including interviews. The product development drawings include sketches from original concept to final design drawings -- most notably for hearing aid battery dispensers. The advertising materials include: sheet music and other documents for the Ray-O-Vac Twins; golfer Arnold Palmer's hearing aid battery promotions; and basketball player Michael Jordan's campaigns. The legal documents relate to several cases from the 1950s with other battery companies over Rayovac's "leak proof" battery design and trademark.
