it's very bright and only comes by every 75years so it's a once in a lifetime event

It is a combination of factors, namely (1) it is bright, and thus visible by many people; (2) it has a 75 year period and thus can theoretically be seen by everyone at least once in their lifetime; and (3) it has returned reliably for many hundreds of years and it therefore shows up regularly in historical records.

Edmond Halley was the first person to predict the orbit, and date of return, of a comet. So his comet is famous because it proves that comets are bodies that orbit the sun.
