Thaddeus Amat was the Vincentian bishop of the diocese of Monterey, California who died in 1878. In 1962, his remains had to be moved. When the casket was opened, his body had not decomposed. Francis J. Weber was assigned to investigate and could not find a natural explanation for the preservation of the remains. He also could not say whether the preservation was due to Amat’s holiness. Amat’s career and funeral are described.
