I echo this. I had two inspirational maths teachers who gave me my love of maths But this was ultimately caused by my chemistry teacher, an old guy who had taught my clever brother 8 years earlier. Handing out the end of term exam marks where I came top he said, “Holmes: 96. Your brother got 98” I never forgave or forgot that remark and vowed, “Right, you bastard, I’m not going to go through life being compared with my brother, I’m doing maths” And so I did. Even did a maths degree.
