description: "Thaddeus Hyatt was an American abolitionist and inventor. In his opposition to slavery, Hyatt organized the efforts of abolitionists in Kansas to have the territory admitted to the Union as a free-state and campaigned for the federal government to aid Kansans afflicted by drought. Hyatt befriended John Brown and provided Brown with financial support; following the raid on Harpers Ferry, Hyatt was investigated by a committee of the United States Senate. When Hyatt refused to comply with a Congressional subpoena and cooperate with the Senate investigation, the Senate voted to jail the recalcitrant abolitionist. As an inventor, Hyatt was a wealthy man, profiting from his invention of iron-and-glass vault covers for admitting sunlight to spaces below sidewalks and pavements. Hyatt also innovated and patented several designs for reinforced concrete floors."
