This is an updated version of an article that originally appeared in March 2007 as part of Snips’ 75th anniversary.

Snips has covered a lot of unique subjects and events in the last 75 years.

Where else were sheet metal and HVAC contractors going to read about dealer open houses, projects that used miles of ductwork or what happened at the Kansas contractor association’s golf outing?

But with so many other things going on in the world, it’s easy to forget what was in Snips decades ago or just last month.

In many ways, Snips was - and is - a news world unto itself. No matter what was going on in the rest of the country, readers could always count on Snips to tell them what those in the sheet metal and HVAC trade were up to.

That doesn’t mean the outside world didn’t impact the magazine. U.S. involvement in World War II curtailed travel and forced the magazine to reduce printing costs. The Sept. 11, 2001, terrorist attacks led to canceled conventions, and economic recessions affect everyone.

However, for the most part, the news in Snips, especially its earlier incarnations, was written to be “friendly (and) close to the reader,” to use the phrase coined by founder Ed Carter. It stayed focused on the sheet metal industry and the people in it.

Here, then, is a sometimes-lighthearted look at some of the notable events of the last three quarters of a century and what appeared in Snips around the same time.

1930s

Nov. 8, 1932

Former New York Gov. Franklin D. Roosevelt wins the 1932 U.S. presidential election, defeating incumbent Republican President Herbert Hoover. Roosevelt’s win is said to be a landslide victory.

Parker Bros. releases the board game Monopoly. According to the Guinness Book of World Records, over 500 million people have played Monopoly since Charles Darrow patented the game in 1935.

• One of the most interesting trends in the oil marketing trade has been that toward concentrating the sale of oil burners in the hands of the distributors of domestic fuel oil. This consolidation of these two allied types of business has only just started and is due for a much more far-reaching development in the opinion of oil burner authorities who have studied the two fields in light of the problems they present.

May 27, 1937

San Francisco’s Golden Gate Bridge opens to pedestrians. The next day, the bridge was opened to commuter traffic. Construction started on the bridge in 1933. The center span of the bridge was the longest of any suspension bridge until 1964, when the Verrazano-Narrows Bridge was erected in New York City.

• The average-sized saloon or tavern, as we know it today, offers a remarkable field for the sale of air-cooling equipment. Last summer in St. Louis, we saw that the idea of blower-cooled taverns was pretty generally adopted. In some cases the blower was hooked up with ductwork, while in other cases it was in one end of the room, with the equipment forcing air across the entire place.

• The bombing of Pearl Harbor saw crystallize, overnight, a spirit of unity among the American people, never before dreamed possible. Knowing thousands in the sheet metal trade as we do - employing contractors, workmen and the leaders of these workmen - we see developing spontaneously, a similar most encouraging spirit of unity, within our own craft.

- Editor’s Page, December 1941 Snips, page 21.
