First of all, my apologies for the inaccuracies. I have gone back to read and researched to find the facts and after reading " THe Three Stooges Filmography" by Jon Solomon.
Accorrding to the book, Jerry died not long after production of "HE Cooked his Goose" was completed in Janaury 1952 here's the qoute from the book: "This film was shot in late December 1951 early January 1952 when Christmas trees were still availible for purchase but not released until July 1952. When Belle answers the door, the Christmas trees are ommited. Curly Howard aged 48 passed away on January 18, several weeks after the film was shot. Although his health continued to deteriorate during his final five years, his fourth wife Valerie and daughter Janie made Jerome very happy. His favorite TV commedian was Jackie Gleason, and he enjoyed watching Beanie and Cecil with Janie."
Curly's fisrt stroke did occur in April 1945, during filming of "A bird in the Head" which was postponed on April 12 out of respect for the death of FDR. Direction Ed Berns recalled the Curly seemed disoriented,pale and incoherent during filming henceforce is why in Larry's 1972 autobiography, he incorrectly recalls Jerry's major stroke as April 1945. Both Mircophonies (which was released first) and Three Troubledoers were shot in May 1945. Before he begin production on "Three Troubledoers" his doctor diagnosed him with hypertension and obseity.
Getting to the alleged brothel incident, After doing research, I have found the 1985 biography by Paul Garner on the Stooges, It is called "Stooges Cronicles" written by Jeffery Forrester and recorded by Paul Garner. unfortunely the book is now out of print.
http://www.3-stooges.com/books/bookrvw.html#Chronicles%20Bio( it was written in 1982 so it contains accounts from the Stooges' surviving families including Larry's daughter who died in 1988, Shemp's widow, Curly's daughters and Joan and Norman Maurer. In the book, Garner who records and narrates, displays rare old family photos of the Howard brothers( including a young Jerry Howard with wavy black hair surrounded by two girls( taken circa 1923.) Shemp with his father Solomon taken in 1915, and newlywed photos of Moe and Shemp with Helen and Gertrude taken in 1925. the incident was have alleged to have occured in 1920. The book said that Curly was very successful with women and was expelled from school for a year after visting a brothel. After the incident, Howard decided not to finish school and decided to pursue acting, it also said that Jerry idolized his brothers and wanted to be like them. Out of the Horwitz chlidren, Shemp was the most misbehaved, Moses was the most insecure often teased about his long girly hair, and Jerry was well manered and loved by everyone. The book also had a still photo of Curly from Monkey Businessman looking pale and disheveled and puzzled with Moe helping him with his lines.
I read the book in 8th grade, My teacher once loaned it to me, now that I found it again I remember better about what I read from it. You can dig deep for this rare book which also includes in interview with Gertrude, and some info about his only son Morton(who died in 1972). Altough this book was written by Jeffrey Forrester, Garner who claimed that Columbia had considered him to replace Shemp in 1955 but was turned down by Moe who told him that him and Larry would be the two stooges didn't publish his autobiogrpahy until 1998.
