Thaddeus Hyatt (born July 21, 1816 in Rahway , New Jersey , † July 25, 1901 in Sandown , Isle of Wight ) was an American lawyer and one of the inventors of reinforced concrete .
Hyatt was a lawyer and entrepreneur. He became wealthy from the invention of a clear glass patch that he made in New York. In the 1850s he was active in the abolitionist movement and founded settlements in Kansas , where a power struggle between opponents and supporters of slavery in the settlement of the new territory had broken out ( Bleeding Kansas ). He also got to know John Brown and, after his execution in 1859, initiated a support fund for his family. He was also supposed to testify in the US Senate on the John Brown matter (he was suspected of having been involved in the occupation of Harpers Ferry), but refused to testify and was imprisoned in the Capitol for three months in 1860.
Hyatt was the American consul in La Rochelle from 1861 to 1865 . During this time he had been accidentally arrested in Paris because he looked a little like Garibaldi .
Hyatt later lived alternately in New York and London - he is said to have crossed the Atlantic over forty times. In his later years he lived mostly in New York City, with a summer home in Sandown on the Isle of Wight. In England he was a pioneer of reinforced concrete construction. In 1874 he built the first reinforced concrete house in London for a fire test and in 1877 he published a treatise on reinforced concrete, in which he also discussed the structural advantages in detail ( An Account of some experiments with Portland-Cement-Concrete combined with iron as a building material with reference to economy of metal in construction and for security against fire and the making of roofs, floors and walking surfaces ). For example, he recognized that the ratio of the modulus of elasticity of iron and concrete is about 20 and the thermal expansion was about the same, he spoke in favor of the arrangement in areas subject to tension and also recognized the advantageous application in bridge construction. He received several patents (1871 to 1881) on reinforced concrete.
