Professor McGonagall

Biodata

Background and history

McGonagall visits Andrew Taylor’s children’s home to explain his admission to Hogwarts. She demonstrates Transfiguration by turning a chair into a goat, answers his questions about school costs, and takes him to Diagon Alley for supplies. His curiosity impresses her, though she warns him against experimenting with magic he does not yet understand 3 4 5.

Alongside teaching, she handles timetables, purchases, staff requests, Ministry correspondence, and exchanges with other schools. The workload leads her to hire Andrew as a paid student assistant after assessing his ability, temperament, and suitability for confidential work 62 74. Their working relationship develops into supervised Transfiguration study, including restricted reading and later Human Transfiguration lessons 82 318 321.

McGonagall also manages school crises and appointments. She organizes the response to a smuggled dragon egg, insists on testing Sirius Black’s teaching before appointing him, and negotiates Professor Nina Martin’s departure only after establishing that Nina wants it 91 210 447.

Personality

McGonagall is stern in class and exacting about safety: she disciplines distractions during Transfiguration and repeatedly sets limits on Andrew’s advanced experiments 29 82 318. Her manner is also protective. She gives Andrew rest when training becomes too demanding, supports Hermione Granger in narrowing her studies, and personally takes Neville Longbottom to see his newly awakened parents 321 374 552.

She is pragmatic without treating standards as expendable. She rejects an unqualified teaching appointment without a trial, refuses a ghost’s offer of money for access to Gryffindor’s sword, and insists that Andrew’s own wishes matter when Dumbledore proposes entering him in the Triwizard Tournament 207 210 482.
