While in high school in the mid 1960s I pumped gas and did small repairs [[tire punctures, oil change, lubes) at a Texaco station for $1.15 per hour.

During college [[late 1960s) I worked as a non-destructive materials testing technician at Magnaflux in Oak Park, MI. Eventually became qualified to x-ray test underground gas pipelines, aircraft wings and aerospace parts - started at 2.75 per hour and in 4 years worked my way up to $4.15 per hour. That was big money in those days, especially with overtime. Took a pay cut to have my first professional position after graduation.
