The use of the phrase "to
gaslight someone" seems to have fallen into disuse, as many folks my age aren't familiar with the meaning of "gaslighting."
Here's the best definition of gaslight as a verb.
---To "gaslight" someone is more than simply to create mischief. It means to manipulate a victim into questioning his or her own sanity and, if all goes well, to thereby actually drive the person insane. The term refers to the great 1944 suspense film "Gaslight" in which a greedy Victorian husband (Charles Boyer) conspires to convince his innocent wife (Ingrid Bergman) that she is going mad, the object being to make his planned murder of her (for her inheritance) appear to be suicide. Mysterious footsteps, "misplaced" objects, and inexplicably dimming gaslights (thus the title) are all part of his nefarious plan.
As a slang term for subtly trying to drive someone crazy, "gaslighting" was first noticed by lexicographers around 1956, though the term probably actually appeared as soon as the film (which was enormously popular) did.---

So how happy do you think I was to find Gaslight Square? This photo almost didn't make it in to this year's show because the reproduction made the subtle arch reflection on the left hard to read and the spiky foliage on the lower right hand side became a solid shape, not separate leaves.
However, Gaslight Square made it in for 5 reasons.
1. the word "Gaslight" and it's meaning
2. the difficulty of reading the uppercase script on the sign, making you work a little to see it
3. the architectural grid that is found in many of the other photos in the show, including "Paula's Union Hall"
4. the use of the word "square" in conjunction with a wall of squares
5. the mirroring of the foliage in "We Will Win"
Really, just the word Gaslight makes it a worthwhile addition and the other details make it a solid enough photo to include without trepidation, but it's really just in place to help the cumulative effect of some of the other stronger photos. Solid enough isn't what I'm feeling, and within 2 years I should have a stronger photo to replace Gaslight Square. By the end of the 10 year run I should have every photo holding it's own.

Whatever with that, Angela Lansbury was great, GREAT, in Gaslight. It was her first major roll and she got an Oscar nod at 17 for Gaslight. She also tore up in National Velvet, but, sad to say, I believe her first film was the apex of her career.
