Ian:
Here are some examples;
I actually remember Dick Wilson. He was the absolute favorite architect of my Dad's and that whole group in South Florida around Gulf Stream and Seminole back in those days. Dick Wilson really was an alcoholic. Those guys would go out drinking together and they sure did get knee-walking drunk. A lot of them were alcoholics, including my Dad.
Dad played golf most every day in the winter in Florida with Tommy Armour. Armour didn't drive a car and Dad would pick him up every morning around 11am (Armour lived right down the street). They'd generally go out to the Delray Beach CC where they had something of a "THRONE" for Armour to sit on.
Armour would sit on his throne and tell stories and hold court while he drank gin bucks and then they all had lunch.
Dad said Armour would have thirteen gin bucks in that session every day, no more and no less, and then they'd go play golf. There was a drink stand at the 14th, I think, and Armour would stop there and have a couple more gin bucks. Depending on how he felt he would either play in or stop right there.
Then Dad would drive him home and his wife would cook him a nice dinner and he would go to bed---eg no more drinks.
Well, Dad and his buddies, including guys like Dick Wilson would go out, mostly down to what was called The Patio in Delray and really do some drinking.
The next day Dad might pick up Armour with a hangover and on the way to the golf course Dad said Armour would regularly launch into him with this admonition:
"Jimmy, how many times am I going to have to tell you that you aren't gonna win a battle against John Barleycorn?"
And Dad would say:
"But Tommy, look at what you........"
Ian, nobody I know today drinks anything like those guys did back then, not even close. Of course there were some lives cut short and ruined by it.
Could they be more creative because of it? That would be very hard to answer.
If those guys back then were more creative or seemed to be than most today something tells me one reason was there just weren't so many people back then to tell them what they could or couldn't do, as there are today.
