The owners of HEROLD & MIELENZ, INC., didn't invent the first electric motor, but their great, great, great grandfather did! The Mielenz Family are direct descendants of Thomas Davenport, a blacksmith by trade, who is credited with developing the first commercially successful electric motor in Brandon, Vermont, n 1834. Davenport began experimenting with electromagnets in 1831 and, not long thereafter, he had constructed his first electric motor. Operated by battery, that first motor was used by Davenport to propel a small car around a circular track, the first recorded instance of an electric railroad. Davenport went on to establish a workshop in New York City and also founded a publication based on electromagnetism and mechanics, printed on a press powered by the electric motor he invented. HEROLD & MIELENZ, INC., has worked closely with a wide variety of original equipment manufacturers, industrial plants, and processing companies, developing solutions for their drive and motor problems and servicing their equipment needs. Each Herold & Mielenz, Inc., employee is a qualified technician, educated in his field, experienced through years of work in the industry, and dedicated to applying true craftsmanship to each individual product and product application developed by the company. It is our understanding of customer needs, our attention to detail, and our reputation for standing behind our work that has made Herold & Mielenz, Inc., a driving force in our field since the mid 20th-century. When you need electric motor drive expertise, coupled with integrity, call HEROLD & MIELENZ, INC.
