Alan Dower Blumlein was born onJune 1903 in Hampstead, London to Semmy Blumlein, a Germanborn naturalised British subject.

He was christened as a Presbyterian, though he later married in a Church of England parish. His future career seems to have been determined by the age of seven, when he presented his father with an invoice for repairing the doorbell, signed Alan Blumlein, Electrical Engineer . His sister claimed that he could not read proficiently until he was 12. He replied no, but I knew a lot of quadratic equations!
