More than 4,000 square feet in three galleries, making up the entire Diamond M Wing of the Museum of Texas Tech, is devoted through Aug. 7 to a traveling exhibit called “Deadly Medicine: Creating the Master Race.”“This is the first time we’ve ever had any exhibit dealing with the Holocaust,” said David Dean, director of museum information services.While the exhibit is open to everyone, Dean hopes parents will pay a visit before determining whether they want their children to see it.The museum’s official statement: “Please be aware that this exhibition presents sensitive material and is not intended for persons under the age of 13.”Dean said, “Some material can be rather graphic, but not grossly so. There are pictures of children who were about to be euthanized during the Nazis’ ethnic cleansing. There also is a picture of a child on an autopsy table. Things of that nature.”
