Obama's Altgeld Gardens account also omits the work of Johnson.
She was already widely known for her pioneering work in pushing officials to investigate environmental hazards at local industrial sites. Spurred by her husband's premature death from lung cancer, Johnson had begun do enting the health complaints of Altgeld residents in the late 1970s. Johnson formed a group called People for Community Recovery and tried to cajole scientists to study possible links between the ailments that residents reported to her and the harmful substances around their community.
One of those scientists, Regnal Jones, visited Johnson in the early 1980s and recalls sitting in her kitchen as she laid out hundreds of index cards listing the illnesses throughout Altgeld. He said he was "blown away" by Johnson's survey.
During that visit, Jones said, he inspected Johnson's apartment and concluded that her heating pipes were insulated with asbestos.
From that point on, Johnson says, she included asbestos in her complaints to government officials.
As Obama became involved in the asbestos issue, Johnson was among those who worked with him.
