I would define the Golden Age of Pipe Smoking, when it was readily accepted in society, as World War II through the late 1980s. It was not uncommon to find a magazine article that published survey saying that women trusted men more who smoked a pipe that those who smoked cigarettes.
I do recall reading a US surgeon general's report, circa 1969 if memory serves, in which the Surgeon General of the United States said "Pipe smokers on the average live three years longer than non-smokers."
In the 1970s, especially in college towns, there was usually a smoke shop, or smoke shop / magazine/bookstore that carried a pretty fair selection of pipe tobacco and cigars. When I was going to school in Eugene Oregon, there was Maddox pipe shop which had both bulk and tinned tobaccos. I still have one of their pipes. Walgreens carried a huge selection of tobacco, as did most drug stores. Fred Meyer stores, owned by Krogers, had a massive selection of tobacco and cigars.
It wasn't until about 1979 after I had moved away from Eugene that I again found a true pipe tobacco and cigar store. It was a magical place and I went to work there part-time. That was my first real introduction to bulk tobacco blends, mostly from Lane Limited and Peter Stokkebye.
I remember the 1970s and most of the 1980s as being great times to be a pipe smoker. Especially when I started buying better pipes.
I think that one could make the case that now, today can be called the Golden Age of Pipe Tobacco as well as pipes.
I left the tobacco business in 1992 and when I started smoking again and January of this year, 2023, I was amazed at the varieties of tobacco I could order as well as the number of artisan pipe makers here in the US and around the globe.
For ease of access to a great variety of tobacco as well as Artisan pipes, I think today with the advent of the internet, we probably have better access to tobacco and pipes than I ever had in the 1970s and 1980s.
I didn't smoke a pipe in the 1960s with the exception of a corn cob that I bought in 1969, and that didn't last too long. I think the first Briar pipe I bought was probably in 1971 while I was in the Marine Corps. So I can't really speak to smoking in the 1950s or 1960s but for the most part, I found a better selection of tobacco's and pipes starting in the 1970s. But coming back to pipe smoking after a 20-year hiatus I am blown away at the variety of tobacco's available and the number of great pipes, both estate pipes and new pipes, that are available today!
