Dan Beach Bradley (18 July 1804 – 23 June 1873) was an American Protestant missionary to Siam from 1835 until his death. He is credited with numerous firsts, including, bringing the first Thai-script printing press to Siam, publishing the first Thai newspaper and monolingual Thai dictionary, performing the first surgery in Siam, and introducing Western medicine and technology. Early life Dan Beach Bradley was born on 18 July 1804 in Marcellus, New York. He was the son of Judge and Pastor Dan Bradley of Whitehall, New York, and Eunice Beach. Eunice died soon after giving birth to her son. As a child, Dan Beach Bradley was an astounding scholar and he loved to read. When Bradley was 20 years old, he suffered a week of deafness and it caused him to examine his spiritual life. Two years after this incident, Bradley dedicated his life to serve Jesus Christ. Bradley thought that his age was not appropriate to study for the ministry so he began studying medicine in the office of an Auburn physician. Bradley took a brief reprieve from his studies due to health concerns, but resumed his studies for a year in Penn Yan, New York. After a year of studying, Bradley attended lectures at Harvard University in 1830 before taking another break to earn money to continue his education. Bradley enrolled at New York University and graduated in April 1833 as a Doctor of Medicine. In November 1832, he had been accepted as a missionary physician by the American Board of Commissioners for Foreign Missions (ABCFM). Bradley had initially wanted to marry one of his two cousins, Jane Bradley or Hannah Goodyear. Jane, however, was only 16 years old and was not in a position to marry Bradley and Goodyear had no desire to serve as a missionary in Asia. After a brief mail courtship, on 5 June 1834 Bradley married Emilie Royce before the couple set sail for Siam. Emilie, like Bradley, wanted to serve God as a missionary. Mission to Siam On 2 July 1834, Bradley and his wife, Emilie departed from Boston for their mission to Bangkok. On 12 January 1835, they arrived in Singapore. Due to monsoons, Bradley and his wife stayed in an unoccupied London Missionary Society home for six months, until the storms finally passed. Bradley and his wife arrived in Siam on 18 July 1835 after an encounter with Malay pirates
