Ralph D. WinterRalph Dana Winter (December 8, 1924 – May 20, 2009) was an American missiologist and missionary who became well-known as the advocate for pioneer outreach among unreached people groups. He was the founder of the U.S. Center for World Mission (USCWM), William Carey International University, and the International Society for Frontier Missiology.

In 2005, Winter was named by Time magazine as one of the 25 Most Influential Evangelicals in America. Dr. Ray Tallman, shortly after Winter's death, described him as "perhaps the most influential person in missions in the last 50 years [who] has influenced missions globally more than anyone I can think of."


Brian LowtherBrian Lowther became Director of the Roberta Winter Institute on May 1, 2010, after serving at the U.S. Center for World Mission in graphic design and publishing for eight years. Brian grew up in Southern California and began following Christ after witnessing the transformative power of Jesus in his father's life. Brian was deeply influenced by Dr. Ralph Winter's thoughts on evil, disease and the cosmic war, so much so that he spent many years developing a yet unfinished novel to illustrate Dr. Winter's thinking. Brian and his wife are members of the Frontier Mission Fellowship in Pasadena, California and have two children.
