Who is June Martino from Grinding It Out and what is their importance?

June Martino was initially Ray Kroc's personal secretary when he was just selling Multimixers. June was a married woman, and even though her husband evaded being drafted for the WWII war effort, she was sworn into the WACs. While enlisted, she studied electronics at Northwestern University. No challenge was ever too big for June, who was the daughter of a prominent German family in Chicago. She had two children towards the end of the War, and after her parents died, she and her husband were nearly fourteen-thousand dollars in debt. She went out looking for a job and that is how she wound up working for Ray Kroc. She was very charming, and business oriented.
