The Clark Building on Liberty Avenue has long been known as a home to jewelers. This small workshop on the building's third floor has the look and feel of a place that's been around for a while, and it has. David I. Helfer founded his jewelry business in 1936, in the middle of the Great Depression. It survives today, still as a family business -- that's David, the founder's great-grandson, sitting at a work station, and his father Ira, standing. Also working at the shop (but not in the picture) are Ira's daughter Dana and father Jack, who's David I. Helfer's son. One employee, Brian Smith, is not related, "but we treat him like family," Dana says.
