Robert Sickinger
Open-knowledge reference entry

William Robert Sickinger (November 7, 1926 – May 9, 2013) was an American theater director, based in Chicago. He was regarded as the founder of "off-Loop" theater, the Chicago equivalent of Off-Broadway. He often cast non-professional actors in his productions, and in doing so occasionally found new talent such as David Mamet, Marilu Henner, Jim Jacobs, and Mike Nussbaum, all of whom were Sickinger proteges.
Early life
Raised in Philadelphia, Sickinger was drafted into the United States Army while still at school and served in the Philippines during the Second World War. He subsequently resumed his studies at Bloomsburg University of Pennsylvania, where he trained as a teacher and first discovered theater.
Chicago theater
Sickinger was able to convince a local movie theater owner to rent him space, and produced a number of plays in this venue during the early 1950s. He was later hired by Hull House Association director Paul Jans to run a theater programme in Chicago. Sickinger chose to produce "challenging, sometimes distressing contemporary plays" on subjects that had never been seen on Chicago stages, mounting productions by Edward Albee, Harold Pinter, Athol Fugard, and Amiri Baraka. Though his choices raised eyebrows, critics generally praised his productions as "revelatory".
Sickinger founded the Uptown Theater, as well as other theaters in more deprived areas of Chicago.
This brief starts where responsible research should: with the source description of “Robert Sickinger” as open-knowledge reference entry. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as open-knowledge reference entry. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 4, 2026. The linked authority identifier is Q42677302. VIAF identifies the subject as 8095167867566223060004. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1926 and 2013.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
