After graduation Washington, following in his father and uncles’ footsteps, and joined the John A. Roebling’s Sons Company around 1900. During his time working for the family business, Washington developed a passion for automobiles and racing. His interest in automobiles transformed into a business when the Roeblings, along with the Kuser brothers of Hamilton Township, New Jersey, paid for the William Walter’s Automobile Company to be moved to the vacant Kuser Brewery in Hamilton Township, New Jersey in 1906. While holding the position of secretary for the Walter’s Automobile Company, Washington also collaborated with the French automobile designer, Etienne Planche, to construct a race-car was named the Roebling-Planche and sold by the Walter’s Automobile Company.
In June of 1909, the Walter Automobile Company filed for bankruptcy. The Roeblings and Kusers acquired what assets where left of the company and invested them into the Mercer Automobile Company that manufactured cars that were safe for and made for individual citizens to drive at their own leisure. Washington continued his love of automobiles and pursued his interest in racing. He began racing Mercer models before they were put on the market to ensure they were safe and well-built.
In 1911, a thirty- year- old Washington made plans for a motoring tour around Europe with family friend Stephen Blackwell, son of the former U.S. Senator Jonathon Blackwell. The final stop of the tour, Southampton, England, was reached in April of 1912. Washington and Blackwell planned to return home aboard a newly constructed ship, the Titanic. Within a week of its departure, on the historic night of April 15, 1912, the Titanic struck an iceberg. Washington worked calmly and diligently to help the women and children on board the sinking ship into lifeboats and on to safety. A Ms. Caroline Bonnell was one of the many women aided by Washington that tragic night. She later told the Roebling family and reporters that the last words she heard from Mr. Washington A. Roebling II was, “You will be back with us on the ship soon again” as he waved to her from the deck of the sinking ship with a smile.
Members of the Roebling family traveled to Halifax, Nova Scotia, to meet ships carrying victims of the Titanic, however; Washington’s body was never recovered. Despite Washington A. Roebling II’s tragic death at the young age of thirty-one, his contributions to the Mercer Automobile Company and his heroic acts aboard the Titanic have become part of the Roebling family’s famous legacy.
