Our company name honors two Canadian pioneers Frederick Fetherstonhaugh and William Still who jointly developed the first electric wagon, which was displayed at the Toronto Industrial Exhibition in 1893. The wagon was the only one developed and was eventually sold in 1912 with unknown whereabouts thereafter.
