What Did the Asbestos Companies Know And When Did They Know It?

The companies that manufactured, sold and installed asbestos products had extensive knowledge of the deadly hazards of asbestos as early as 1920. Yet, these corporations waited decades to provide warnings to workers and to the general public. In some cases, warnings were never provided.

In addition to this actual knowledge on the part of asbestos corporations, the evidence available in medical books and journals revealed the dangers of asbestos exposure long before millions of American workers were exposed.
