Who wrote the tagline for the film Alien, 'In space no one can hear you scream'?

I've been researching the movie poster as part of a project for uni, and during my searches in books and online I've come across contradicting evidence, either it was the designer Philip Gips wife Barbra Gips, or a man named Steve Frankfurt who wrote many other taglines

barbara gips wrote that tagline. steve frankfurt took out an ad in variety stating he was wrongly credited.
