DAVID FISHER is a missionary radio broadcaster working jointly with Trans World Radio and the Slavic Gospel Association. He is director and editor-in-chief of Radio Academy of Science (RADAS). Fisher believed that scientific atheism was preventing many from accepting Christ, so he began writing scripts for a broadcast which countered atheistic spins on scientific issues, and included interviews with believers professionally involved in the sciences. Nearly 30 years later, TWR’s Truth in the Test Tube program and webcast continues to make a difference in the lives of students and young adults. He is co-author of Scientists Who Believed with Eric Barrett.
