Artisan Information
My interest in decorative aluminum began in 1990 when I attended the first Hammered
Aluminum Show.  I went seeking  information about several pieces of Kensington ware
that I had.  Originally from the New Kensington, Pa. area where Alcoa was located and
Kensington ware was made, I had an interest in whether it was collectible.  Once I saw
the amazing variety of aluminum art I soon forgot about the main reason that I attended
and began my journey looking primarily for pieces of  hand hammered / wrought
aluminum.  I began collecting various pieces not really knowing anything about them and
soon had quite a collection.  I began wondering about pieces like where and when they
were made and who produced them.  I was surprised to find that not much was known
and I then began doing my own primary research into various producers and have
amassed a large amount of source materials. I have also conducted interviews with many
of the original artisans.  I have written articles for antique journals and magazines and
have also authored monographs about several artisans including
Bruce Fox, Clayton
Sheasley, Cartwright Castle-Art and John Findley/Frank Deets
. These are
professionally researched, written and spiral bound.  I continue to research various
artisans and am particularly interested in those from Pennsylvania. I welcome information
and pieces about the following producers;
HC, Arthur Armour, Palmer Smith,
Wendell August, Laird-Argental, Mansfeld, Hyman Blum and L. Gene Stewart
.  
My research has also led me to vintage dies which I have acquired and use today. My
goal is to both preserve them and spread their art to new generations.
These are original pieces made by Henry Mansfeld.  The
silent butler has a wonderful stylized gazelle motif.  The
candleholders also have a graceful design incorporated into
them. His pieces were marked either H. Mansfeld or
Mansfeld P.P.P CO. Unfortunately many of his pieces also
went unmarked making identification difficult. Also his
production output was somewhat limited making his pieces
scarce.
Henry Mansfeld was a very skilled blacksmith who immigrated from Germany to
Pennsylvania in the early part of the last century.  He worked for various companies
fabricating ironwork. In the 1930's he began producing his own line of aluminum gift
ware using steel dies that he designed and engraved himself.  Mansfeld was a self taught
artist and drew inspiration from nature and art books to design his dies.  Most are very
stylized renditions of a floral nature but he also did some with horses and birds. They
reflect the Art Nouveau and Art Deco influences that interested him at the time.  He sold
the dies in the 1960's and they lay unused but well cared for until 1997 when I acquired
them along with his tools and forms. In 1999, I began making pieces with them and
marking them "
Hand Wrought Mansfeld by Dennis" in honor of him.
Clever original piece by Rev. L. Gene Stewart using 2 different dies.  The
Praying Hands are surrounded by Appleblossom.  His pieces are marked
"Hand Wrought by L. Gene Stewart". The die motifs are very straightforward
and realistic, reflecting various plants such as dogwood, daisy and pine but
there are also dogs, deer and ducks and are indicative of the popular designs
of the 1940's and 1950's .
Rev. L. Gene Stewart began producing aluminum in the late 1940's and continued
throughout most of his life. He designed and engraved his steel dies to use in making
aluminum giftware. As a minister, he used his aluminum work to both ease tension and
help raise money for various parishes.  I acquired these dies, forms, tools and hand stamp
in 2003 and now make items with them.  They are marked "
Hand Wrought L. Gene
Stewart by Dennis"
to honor him.

A grouping of original pieces by The Forge with the Magnolia
motif.  It is a magnificent die that I now have and use on a variety
of pieces. The die was engraved by the master engraver
Steve Adams for The Forge. Their dies that I have are very
detailed depicting various garden scenes along with other floral
designs and many smaller dies for Christmas ornaments, jewelry
and bookmarks.
The Forge began in Pennsylvania around 1996 but grew rather quickly and eventually
after moving to Ohio they opened stores in both Michigan and Virginia.  Financial issues
forced their closing in 2007 and in 2009 I was able to acquire some of the dies that they
used in their production.  Most of these dies were engraved by Steve Adams and the
pieces that I make are marked
"Hand Wrought SA"  to honor him.
Dennis Wildnauer is a retired Horticulturist who developed a
love of aluminum art so I traded in my trowel for a hammer.
Since 1999 I have been hammering out pieces of aluminum
giftware art with the above dies and also with some of my own
original designs created with various stamps, tools and dies.  
These pieces are  marked
"Hand Wrought by Dennis"  Among my
favorites are Christmas Tree, Circle and Swirl and Mosiac.
A. J. Hoover (Aaron J. Hoover) was an industrial arts teacher at
The California State Teachers College in California, Pa. from 1936
to 1967.  He taught various subjects under Industrial Arts including
hammered aluminum.  He engraved at least 2 dies for teaching
purposes; a larger Pine die(an original tray from that die is shown at
left) and a smaller Aster die. I purchased the dies in 2011. These
pieces are marked "Hand Wrought AJH" to honor him.  
Interestingly, L. Gene Stewart went to this college and likely took
classes from A.J. Hoover.  His Daisy die is very similar to the
Hoover Aster.
