I know in their gallery the University has short-listed this as a possible portrait of Alexander Gerard (1728–1795), Professor of Divinity at King's College Aberdeen, but they aren't sure. I think it matches the caricature #2 of Sapient Septemviri, 1786 (see NPG website: http://www.npg.org.uk/collections/search/portrait/mw192103/The-Sapient-Septemviri-The-Seven-Professors-of-Kings-College-Aberdeen). Very similar robes, wig, nose, face, cheeks, eyebrows, etc.
Also the sitter in this portrait is wearing similar robes as Alexander Gerard's son Gilbert in his portrait at the same gallery, who succeeded him at the college: http://www.bbc.co.uk/arts/yourpaintings/paintings/gilbert-gerard-17601815-dd-105152
From page 118 of Volume X of the Aberdeen University Review (1923), the following snippet has been taken: "....there is a proper portrait of Alexander Gerard in the Senatus room at King's College, and one of his wife as well. He is a nice-looking man, wearing a small white wig....". Perhaps this volume could be consulted by one of the Aberdeen University researchers to see if the rest of the description fits the discussion portrait.
Good find, Kieran. I've managed to cheat a bit more out of the Google snippets: "He is a nice-looking man, wearing a small white wig, such as one associates with bishops. His face is gentle and refined, the expression perhaps a little too suave, but a judicious blending of the portrait and the caricature would probably give the proper balance." That seems a fair enough description.
It continues (re his wife's portrait): "Mrs. Gerard must have been a charming — a consciously charming — lady, and a dressy one too, as her blue satin gown and the Alencon lace of her sleeves testify. A dainty dog-collar of lace and pearls surrounds her neck, and she wears a pink rose in her bodice. The dress must have been a quite lovely one and shows her to have been a person of great taste. She holds a little ... ". That's as far as I can get. I thought that might enable us to spot his wife's portrait (and see if they made a a pair), but in fact I see she's already identified: http://bit.ly/2zEYZqR
They seem to be (if measured in the same way) of slightly different sizes, and not a pair as such - but they go together reasonably well. What about the frames - are they the same? And are there any other possible candidates for his portrait in the Collection (there are over 400, and I don't have time to check just now)? If not, then it pretty much has to be him.
Although not the subject of this discussion, the University of Aberdeen's portrait of Mrs. Jane (aka Jean) Gerard, the eldest daughter and co-heiress of Dr. John White (aka Wight) of Colnae, to whom Alexander Gerard was married on the 14th June 1757, might have been painted by Allan Ramsay. See attached composite for this consideration.
See the attached clipping from "Officers of the Marischal College and University of Aberdeen, 1593-1860" for a biographical entry for Alexander Gerard and the mention of the University of Aberdeen's possessing a portrait of him.
In 1754, Gerard was a founding member of the 'Select Society of Edinburgh', which also had Allan Ramsay in its number. Gerard and Ramsay were both subsequently involved in the writings of the Scottish Enlightenment in the years 1756 and 1757.

Could it be that the portrait of Alexander Gerard was also by Ramsay?
Additionally, in regards to the above reference to Alexander Gerard's caricature #2 of Sapient Septemviri, 1786, see the attached composite and also the clipping from page 77 of 'A Series of Portraits and Caricature Etchings by the late John Kay, Miniature Painter, Edinburgh' by Hugh Paton (1842).
No one has made any suggestion as to the artist, probably a painter of the generation of William Cochran, William Millar and David Martin. Was there a portraitist in Aberdeen to whom one went at this date?
The portrait of Mrs. Gerard needs cleaning/restoration, but it strikes me as inferior to the other portraits in the composite. I suppose it might still be a Ramsay, but I would want stronger evidence to accept it as such.
Update: the link I supplied in 2015 for Alexander's son portrait (Gilbert Gerard) is no longer valid, it's on this site now as: https://artuk.org/discover/artworks/gilbert-gerard-17601815-dd-105152
Purely for the sake of comparing their Doctoral robes, attached is a composite of our sitter with Robert Hamilton (1743 - 1839) and Hugh Blair (1718 -1800). The three tassels on each man's arm indicate the status of their positions. If our man is Alexander Gerard, then all three of them were founder members of the Royal Society of Edinburgh in 1783.
Well spotted Kieren, I didn't know that detail about the robes, I'm coming from the family history angle. I found this detailed list on the founding members of the Royal Society of Edinburgh... (https://www.rse.org.uk/cms/files/fellows/biographical_index/fells_indexp1.pdf ) and it verified that Alexander Gerard was a founding member of the society in 1783, as were the other 2 men you supplied.
The Uni of Aberdeen which has the proposed portrait of Alexander Gerard, had listed it as possibly being 'Matthew Mackail Sen (1657-1696)' - (Google Books: 'British and Irish Paintings in Public Collection...' -p127) he graduated Kings College in 1696 and appears to have died that year (wikisource), and thus wasn't alive in 1783. So the portrait can't be of him.
So you have supplied another piece of evidence to strengthen the case that it's Alexander Gerard's portrait. Good work.
