In 1850 an American doctor, Dr. Gerrit P. Judd purchased 622 acres of ranch land at Kualoa for $1300, and also the island of Mokolii just offshore, from King Kamehameha III. Dr. Judd was the first person to translate medical journals into the Hawaiian language for King Kamehameha and so the king was very grateful for his works. In 1860 Dr. Judd bought a further 2200 acres. Then in 1880 Dr. Judd's son Charles bought another 1188 acres. Today there are about 4000 acres of land.
