and work with the famous urban anthropologist Elliot Liebow, author of “Tally’s Corner” and “ Tell Them Who I Am: The Lives of Homeless Women,” motivated him to speak and write about problems of the homeless. In 1989 he devoted several months to living as a homeless person in several cities throughout the United States. He conducted extensive interviews with “other” homeless persons, and sent the findings by mail to Liebow. These correspondences formed the basis of a series of lectures about homelessness given by Liebow and Barker to various government agencies, universities, and civic groups. Forensic social work After Barker retired from The Catholic University to devote more time to the dictionary and to homeless advocacy, he testified as an expert witness in courtroom trials, primarily involved in family dissolution disputes and custody issues. He conducted workshops for social workers on how to prepare for courtroom testimony and to conduct forensic investigations to be used in legal proceedings. He developed a curriculum for universities for a new specialty, forensic social work, and with lawyer Douglas Branson of the University of Pittsburgh School of Law, published the first text on the subject, “ Forensic Social Work”, now in its second edition. This text is now used in many schools of social work for their courses on forensics and legal issues.
