A few did; never the majority. Here are the facts about scientific cooling predictions:
BTW, greenhouse effect warming predictions go back over 100 years.
UPDATE
@SW-User asks
How many were subject to peer review?
Fair question. Here's the source: https://journals.ametsoc.org/view/journals/bams/89/9/2008bams2370_1.xml And here's an excerpt:
S U R V E Y O F T H E P E E R - R E V I E W E D L I T E R A T U R E . One way to determine what scientists think is to ask them. This was actually done in 1977 following the severe 1976/77 winter in the eastern United States. "Collectively," the 24 eminent climatologists responding to the survey "tended to anticipate a slight global warming rather than a cooling" (National Defense University Research Directorate 1978). However, given that an opinion survey does not capture the full state of the science of the time, we conducted a rigorous literature review of the American Meteorological Society's electronic archives as well as those of Nature and the scholarly journal archive Journal Storage (JSTOR). To capture the relevant topics, we used global temperature, global warming, and global cooling, as well as a variety of other less directly relevant search terms. Additionally, in order to make the survey more complete,...
In short, that article ONLY covered peer reviewed literature (it should be noted that climate science as we know it today didn't really exist in the 1970s). There is a lot more history discussed in that article; one influential cooling paper
J. Murray Mitchell, who, in 1963, presented the first up-to-date temperature reconstruction showing that a global cooling trend had begun in the 1940s.
However, Mitchell's data was biased towards the northern hemisphere.
It was not long, however, before scientists teasing apart the details of Mitchell's trend found that it was not necessarily a global phenomenon. Yes, globally averaged temperatures were cooling, but this was largely due to changes in the Northern Hemisphere. A closer examination of Southern Hemisphere data revealed thermometers heading in the opposite direction (Damon and Kunen 1976).
Meanwhile, other scientists were collecting much better data on prior ice ages. Climate science as an independent discipline was beginning to emerge.

@ElwoodBlues How many were subject to peer review?
@SW-User A fair question. Short answer is all of the ones in the graph. Long answer is important enough that I updated the above answer to keep all the info together.
