with the money from the sale of their company to eastman kodak, they began making steam cars. in 1899, they produced and sold over 200 cars, more than any other u.s. maker. in 1899, freelan and his wife flora drove one of these cars to the top of mount washington in new hampshire, the highest peak in the northeastern united states. the ascent took more than two hours and was notable as being the first time a car had climbed the long mount washington carriage road; the descent was accomplished by putting the engine in low gear and using the car's brakes. the twins later sold the rights to this early design to locomobile, and in 1902 they formed the stanley motor carriage company.
