When I first met the sons of Allen Grinberg, grandsons of Meyer Grinberg, they told me that they had seen the shovel their grandfather used at the groundbreaking for the second synagogue, but they had no idea where it was.  A year-and-a-half later, they found it!  And here it is!

With this spade “Myer Grinberg” broke ground for the new synagogue “Rodef Sholem” at Homestead Penna.
