For the past two years the Out4STEM program has hosted a Masquerade event around the time of Halloween. We started this year's event on October 29, 2015, with a discussion of Dr. Henry Anonymous who said to a convention of the American Psychiatric Association in 1972. He had to to discuss himself or he would have been fired from his job at Temple University. Homosexuality was still classified as a mental illness at that time. 22 years later, Dr. John E Fryer revealed that he was "Dr. Henry Anonymous." Out4STEM honors this piece of LGBT history with a mask-decorating session where participants decorate a mask with what they show on the outside and what they hide written on the inside. This forms the basis of a discussion on individual identity and the perceptions of others.
