Like visitors today, the Barkers and their guests entered the mansion through the grand bronze doors and carved stone vestibule. Stepping into this formal foyer ensured the first impression of prosperity and influence. This space, an integral part of the 1905-1909 expansion of the original house, serves as a captivating introduction to the Barker family’s illustrious history in Michigan City.

Dominating the north wall is the commanding portrait of John Barker, whose entrepreneurial spirit laid the groundwork for the family's ascent to prominence. From humble beginnings in the dry goods business when first arriving in 1836, rising to the helm of the Haskell & Barker Car Company, the senior John Barker's legacy resonates through the generations. Directly below his portrait is a photograph of his son, John Henry, whose stewardship ushered in an era of unprecedented growth for the company. Pictured alongside John H. are his second wife, Katherine Fitzgerald Barker and their daughter, Catherine.

The foyer’s ambiance evokes that of an English country manor house, with heavy wood furniture and torchieres casting a warm glow. While the antlers that once adorned the walls are now absent, the foyer's allure remains undiminished, punctuated by Simon Elwes' masterful portrait of Catherine Barker Hickox. This painting by the esteemed English artist preserves the essence of the Barker Mansion's past, ensuring that each visit to this grand space is a journey through time.

Building on the commitment of earlier generations, the Barker family continues to honor its legacy of philanthropy. The Barkers were founding contributors to Michigan City’s first public library, the first YMCA, St. Anthony’s Hospital, the bandstand in Washington Park, and numerous other institutions. The Barker Welfare Foundation, founded by Catherine, continues to support non-profits in the community today.
