No, they are not. My sister, Eve Kosofsky Sedgwick, the
professor of English literature, writer, critic, and poet who sadly
passed away a few days ago (April 12, 2009), acquired her last name
through marriage to Hal Sedgwick, a researcher and professor in the
field of the psychology of visual perception. Thus, any
relationship to other Sedgwicks would only be through marriage. As
far as I know, Kyra Sedgwick is not related to my brother-in-law,
Hal. David Kosofsky, New Orleans
