[Al Publican]

A photo of a vacant commercial building on E .McNichols with a Mac-O-Lac advertisement popped up online recently. Was that a Detroit based company? They went out of biz years ago?

In Memoriam
Walter L. Field
1901-1999
Entrepreneur and Man of Letters
When Walter Field, “a man for all seasons,” passed away
in December 1999, the Detroit Jewish community lost a major
contributor to its present and its history. His life spanned the
entire twentieth century, and he had a long and remarkable
career ranging from business and journalism to Zionism, education, and poetry.
Field came to the United States through Canada as an illegal immigrant from
Poland, and made his way to Detroit, where he established the Mac-O-Lac paint manufacturing company in 1931. His lifelong passion was to foster Jewish education
opportunities for young people. He was active in the Detroit Zionist movement, and was
an influential member of Congregation Shaarey Zedek.
