Oh and by the way, considering Wendell Wagner’s obvious assertion for his love of “facts”, let’s put this to bed:
He didn’t “drop out”, as you mention, nor did he suddenly “move to another country”. What’s true is his family moved to Milan in 1894 but he stayed in Munich and took examinations (he wanted to study electrical engineering at the ETH in Zurich). These he failed after which he renounced German citizenship and attended a secondary school in Switzerland, as is mentioned here and here. He gained his certificate in 1896 and finally enrolled in his beloved ETH.
He graduated from the ETH in 1900 as a teacher of mathematics and physics. He wasn’t impressive enough to get any type of position, so much so that he was mailing around universities, hoping some guy would hire him. Although he taught part-time as a temp, he was much disillusioned, stating
"I have given up the ambition to get to a university … "
Well, his luck pulled through and his buddy’s father landed him a job at the Swiss Patent Office.
We have to bear in mind that when we talk about Einstein I don’t think you can point to any remarkable academic achievement when explaining his success. Indeed, it seems contrary. The guy apparently had problems speaking at a young age (“silence is genius in reserve”), and most accounts of his academic career that I have read term him as an “average” student.
His great discoveries, ideas and principles were mostly forged out in his spare time, for example whilst working in the SPO. For me that’s what distinguishes him - the solitary quest for truth.
