Perhaps not so much of a need to bring
Harry Simpson out of obscurity, given he made it to the bigs in the wake of "integration", but even then I doubt he is anywhere near as familiar to most as his contemporaries.
Born in Atlanta, Harry Simpson's pro career commenced after he returned from serving in WW2, with him spending three seasons in the NeL with the Philly Stars. After a couple seasons in the minor league system, Harry made his MLB debut with Cleveland in 1951 but struggled in his time there and by 1954 was back in the minors with Indianapolis, with his 4-yo son tragically killed in a car accident during this period. The remainder of his MLB was a peripatetic one involving a seemingly endless number of trades (including one to the Yankees in 1957 as fallout from the infamous
Copacabana nightclub incident continued) - indeed, he played for five different clubs during his eight seasons in the bigs - and somewhat disappointing performances on the field. He finished his MLB career after the 1959 season, leaving with a 269/334/403 line and 76 home runs - including grand slams for four different teams. BBRef has him earning a tad under 6 WAR for his career, while EC has his full MLE career set at around 14.
His EL career is coming along swimmingly indeed. Harry entered the league before the 1975 season as a FA and was signed by the Giants, for whom he still plays. His performances have improved with each subsequent season - he won last season's Kindling Award for the FC at LF and, as you might have noticed in the recent update, he just won his first monthly hitting award. Looking forward to seeing his blossom further from here.
