ABM History Timeline

  • Before the Broom

    The Rosenbergs
    In 1909, Morris Rosenberg invests $4.50 in a bucket, a sponge, a mop, and a company’s future. Serving merchants on San Francisco’s Fillmore Street, Morris turns a profit of $3.50 on his first day.
  • A Window on the Future

  • World’s First

    Stanford

    Winning a contract to clean Stanford University makes us the first janitorial contractor in America to clean a major college campus. Making a mark for ABM’s employee culture, a future president of the company (Morris’ son Ted) is sent there on his first professional assignment, as a janitor.

  • Coast to Coast Expansion

    ABM in New York

  • Keeping a Whole World’s Fair Clean

    World's Fair

    The World’s Fair on San Francisco’s Treasure Island asks ABM to be responsible for 500,000 square feet of space, including entrance halls, pavilions, exhibit palaces, 400 restrooms, and more. To get the gates open on time, trucks have to haul 280 tons of debris off the newly created island. Our executives request 400 union workers within 24 hours. On opening morning, the site is ready.

  • The Giant Janitor

Survivor Jan Demczur, an ABM window washer, uses his squeegee to open a trapped elevator, saving not only himself, but the lives of everyone stuck inside. To honor Demczur’s bravery in leading those trapped with him safely out of the building, his squeegee and ABM uniform were later inducted into the Smithsonian Institution in Washington, D.C. At the time of the attack, the WTC is ABM’s single largest client, with approximately 800 janitorial, engineering, and lighting employees caring for the site.
