I attended The Central High School of Philadelphia from September 1967 to June 1971 (230th class). When I was in the 11th grade (1969-1970 school year) I used to hang out during lunch period with Steven and Howard Chanin, fraternal twin brothers. The Chanin brothers and I had attended the same elementary school, Rowen Elementary School ("Education is not a mere means to life. Education is Life." -- William Rowen). Maybe the Chanins were in Miss Perry's kindergarten class at Rowen, but I can't remember now. In junior high school they were enrolled in a special program that combined the 7th and 8th grades, so they had started high school a year earlier than I and graduated in June 1970. Coincidentally, they attended Penn State (where I went to college); they majored in psychology. I think they live in Boulder, Colorado now.
In any event, the Chanin brothers and I used to play a primitive version of penny hockey every day at the lunch table in the cafeteria. Some days another student would join us. He was in the Chanins' class, the 229. I can remember his name, despite the fact that my only contact with him was a few encounters in the cafeteria. His name was Alan Bedrick, whose last name happens to be the first name of the famous Czech composer Bedrich Smetana, who wrote the opera, The Bartered Bride (Die Verkaufte Braut). (Smetana is Yiddish for sour cream. And no, Smetana's father was not named Latka. Latka Gravas was the name of a character on the 70s sitcom, Taxi. But I digress.)
Alan Bedrick is now a medical doctor who specializes in neonatology. Coincidentally, Dr. Bedrick earned his medical degree at Penn State's medical school in Hershey, Pennsylvania.
Aside. I can still remember that in their senior year the Chanin brothers read Franz Kafka's novel, The Trial (Der Prozess), in German class. I studied French, not German; that I can remember their reading Der Prozess is a tad peculiar.
The Moldau, a nationalist tone poem by Bedrich Smetana, famously employs a melody that is the basis of the Israeli national anthem, Ha Tikva, The Hope.
