Unidentified female Hogwarts teacher

This Female Professor was teaching at Hogwarts School of Witchcraft and Wizardry from 1994 to 1997 at least and was seen at the Welcoming Feast each year.

Career at Hogwarts
This teacher was in a career of teaching at Hogwarts School of Witchcraft and Wizardry by at least 1994, she was seen seated at the Staff Table in the Great Hall when the school opened its doors to Durmstrang Institute and Beauxbatons Academy of Magic for the holding of the Triwizard Tournament. She was later seen attending the Yule Ball and stood with Minerva McGonagall, Severus Snape and Albus Dumbledore watching over the proceedings acting as a chaperone. To the Yule Ball she wore red robes. She was again seen seated at the Staff Table in 1995, sitting next to Sybill Trelawney as she made a mess of eating her meal. This year, Hogwarts would under go inspection from High Inquisitor Dolores Umbridge and it is presumed that as a teacher at Hogwarts, she would also have been inspected by Umbridge.

In 1996 she was seated at the Staff Table again for the Welcoming Feast, this time she sat in the seat to Albus Dumbledore's left and on her other side sat Rubeus Hagrid. This year was an eventful year at Hogwarts, the castle was infiltrated by Death Eaters and her employer, Albus Dumbledore was killed by Severus Snape on the top of the Astronomy Tower.
