Barzillai Gray (October 1, 1824 – December 25, 1918) was an American judge. He graduated at the University of Michigan in 1845, A. B., and was admitted to the bar in 1853. He settled in Wyandotte, Kansas, but later moved to Leavenworth, Kansas, where he was elected judge of the criminal court. In 1876, he was appointed private secretary to Governor George T. Anthony, of Kansas. At the close of Governor Anthony's office, Judge Gray moved once more to Wyandotte, where he held many offices among them that of probate judge. He was, however, best known for his real estate and development plans. He was instrumental in planning several additions and laying out roads and took great interest in the future of that portion of the city known as "Riverview", where an effort was made to establish a market and grain exchange. As territorial attorney for Wyandotte district, Gray was the first man in Kansas to prosecute liquor cases.[1]
