What sociologist used the term stigma to refer to characteristics?

The concept is that of the American sociologist Erving Goffman, in his well-known book of the same name, where he talks about the sociological notion of the term as part of a despised social group. The term means a condition or trait that causes the person to be included in a negative social category where they are culturally inferior.
