Robbins still has mementos from serving five years in the U.S. Army during WWII.
The pair met after Robbins had been looking for someone to wash his clothes, and Pierson's mother agreed to help. However, the romance didn't last that long because Robbins had to depart for the Eastern Front to fight against the Axis Powers.
The love story of this American veteran who fell head over heels in love with a French woman during the global war is proof that "true love never dies".
During their emotional reunion, Pierson asked Robbins why he had never returned, and never gotten in touch.
As the war ended, she even learned some basic English phrases in the hope that Robbins would return.
Instead, Mr Robbins - who enlisted in the 26th Infantry, First Division in 1940 and later volunteered to serve in a bakery battalion - returned to the USA where he met his wife of 70 years Lillian, who passed away in 2015 aged 92.
"You can make signs, do things and make out", he said with a laugh. She passed away in 2015 at the age of 92.
Ganaye recalled the moment 75 years ago when Robbins left in the truck, telling Today, "I cried, of course, I was very sad". Right after that memorable encounter, the pair fell in love with each other.
The pair, who both married other people but are now widowed, met at the retirement home where she now lives.
Mr Robbins then pulled out the photo of the Frenchwoman he had kept for so many decades.
A few weeks later, he went to France for the commemorative ceremonies marking the 75th anniversary of the D-Day landings where journalists had managed to track her down.
She was thrilled to see him, too.
The journalists organised a reunion for the both of them and it's so sweet!
Robbins and Pierson immediately embraced when they were reunited, gazing into each other's eyes with adoration and joy.
"I'm going to show you something".
During the video, Mr Robbins was also seen pulling out an old photograph of Jeannine as he said: "This is you".
"He said he loves me". In a report published by Unilad, the two had reunited for the first time in 75 years-thanks to a group of French journalists.
Upon meeting, the former United States soldier showed the old black-and-white photo he had kept of Pierson all those years. "I wish he had come back".
"I always thought of him, thinking maybe he'll come", she admitted.
