History

1975

Land donated: the beginning

I thought it was about time someone did something for the ol' town. So many take so much from Dubuque, but leave so little behind.”

-JACKSON (MAC) MARSHALL

In 1975, “Mac” Marshall (1894-1977) donated 51 acres of land -- 36 acres of meadow and about 15 acres of walnut timber -- to the City of Dubuque with three stipulations:

that the land would always be used as a park
that he could reside in the farmhouse whenever he wanted
that city government begin developing the land within a year

1976

Tri-State Garden Club formed

In 1976, Jim Schwarz formed the Tri-State Garden Club with the purpose of establishing a botanical garden in Dubuque and learning about gardening together. Also, at that time, Frank Hardie had an interest in establishing an arboretum. A collaboration began.

1980

City leases 16 acres of land

The Dubuque Parks Department initially leased 16 acres of Marshall Park to seven Tri-State Garden Club members (Jim Schwarz, Gene Heinemann, Mel Gottschalk, Ambrose Hoeger, Marlyn Bausman, Jack Frick, Frank Hardie) with each member contributing $20. These visionary volunteers started it all by planting the trees, bushes and plants, and erecting fences and arbors.

The first officers of the association:

Frank Hardee, President
Jim Schwarz, Vice-President
Mel Gottschalk, Secretary
Ambrose Hoeger, Treasurer

At the time, there were just two structures on the property:

Marshall's farmhouse
an old hay barn with a lean-to cowshed

The Dubuque Arboretum & Botanical Gardens had begun.

Water was carried in gallon jugs to water the plants.
Renovation of the barn into a visitor center began. Ron Jungers was the designer and constructor of the project.

1982

Volunteers began to build and plant

Gene Heinemann quickly became the leader of the ongoing projects. And Gene and Jim Schwarz took many plant and tree acquisition trips.
Volunteers built a rail fence; planted bushes and trees; drilled a well; gutted and remodeled the barn; and removed the old cow shed. [Photos below.] Gene Thompson and Bill Vandewill were major players in the outdoor projects.
The first 8 raised annual beds, edged with wood, were planted.
The Jodi Bausman Memorial Garden was created with prairie grasses, wildflowers, and old garden roses: Prairie Garden
The barn loft was roughed in and restrooms were completed.
