The author (right) with his Dad (center) in 5715 in the synagogue sukkah
The synagogue in Manhattan at that time was a stately place with formal services, led by a professional Hazzan. My dad wore a robe and high hat - black during the year and white on the High Holy Days.
He was famous in the city for his sermons. He labored over them for hours. He would send "releases" to the local papers (like the NY Times' 230+ citations of his sermons -- here in online book form) to let them know about what he would be preaching on Saturday. Those were the fifties and the Times and other papers covered the Saturday and Sunday sermons. Frequently we would look around the sanctuary to see if the reporter from the Times was present. We'd know because he'd sit in the back and be writing feverishly on his reporter's pad. (Not iPad... real paper pad.)
My father was ambitious especially about increasing the attendance at the services. We had to count the number of people in shul and discuss that at the lunch table. Then he'd ask us how the sermon was and we all answered enthusiastically every week, "It was terrrrrrific!"
