Hahne and Company

Starting in the 1950s, the company began to focus slowly on suburban growth. The Montclair store was replaced with a larger full-line branch, designed by Fellheimer & Wagner, with Roland Wank, and the original location became Hahne's Budget Store. In 1963, a location in Westfield was added. The firm did not enter the growing mall market in New Jersey until the 1970s, and this cost the chain valuable time in keeping up with its competitors.

Hahne's remained too focused on its Newark Store in the 1960s. The Montclair store was built too small to be a true department store, management was so pressed for selling space in Montclair that it had to take their Christmas decorations to the Newark flagship just to store them. Although the Westfield location was attractive, Hahne's lacked the customer base to compete with the nearby Lord & Taylor in Millburn, Saks Fifth Avenue in Springfield, and Bonwit Teller, B. Altman & Co and Bloomingdale's in Short Hills.

Newark declined badly in the 1960s and 1970s and the division, with most of its sales volume coming from the Newark flagship, went down with it. The Newark location lacked parking and was in a neighborhood that suburban shoppers felt was unsafe. Alan Kane, the executive in charge of their repositioning had some good ideas but they were too little and too late to save the chain. The stores below that Kane opened are still operated as Lord & Taylor locations, or are occupied by the chains that bought them, while the three that he inherited are all gone except for Westfield.

During the course of the 1970s and 1980s, the chain attempted to reach out to a broader shopper demographic with mixed results. In 1978, parent ADG appointed Alan Kane, a graduate of Wharton School of Business, as CEO of Hahne & Company. Kane oversaw the planning and opening of two new locations (Woodbridge Center and Rockaway Townsquare), and he steered the company toward a more focused, upper-market clientele. The Livingston Mall location was branded the company's "flagship" during this time.

In mid-1986 Hahne & Co. announced a major reorganization that would see not only the downtown Newark location close, but the corporate offices would leave Newark as well. ADG acquired the large Gimbels location at the Garden State Plaza, with plans to use two floors for Hahne's first location in Bergen County, and the lower level as Hahne's temporary corporate offices. Shortly after this plan was announced, ADG was sold to the May Department Stores Company, and per May Co.'s policy, major plans were put on hold until May's officers had a chance to review the details. After careful consideration by May, the Newark store was closed in 1987 and later in the same year a two-level location opened in the former Gimbels Garden State Plaza location. Hahne's offices were relocated to leased space in Woodbridge, near the company's distribution center that had opened in 1985.

May contemplated running Hahne's as a more contemporary focused chain that would compete with Bloomingdales, but Kane left the brand after a management shakeup had changed the overall direction of the company. By 1988, May decided to retire the brand and convert most of the stores into new locations for its Lord & Taylor banner.[8][9]

Montclair store in 1951

In 2007, after sitting empty for approximately 20 years, the architecturally significant 1951 Montclair store was demolished and replaced by a new development housing condominiums known as Siena At Montclair.

In January 2013, after sitting empty for almost 30 years, it was announced that the Newark flagship store would be renovated with a Whole Foods Market and retail arcade on the ground floor and 83 residential units above.[7] A nine story addition with 77 residential units[7] was constructed on the Halsey St. side of the building and underground parking as well.[10][11][12][13] On October 9, 2014, nearby Rutgers University announced that they would open a new arts center on three floors of the Hahne and Company building.[14] The arts center will be called "Express Newark", and will include an arts incubator, media center, design consortium, print shop, portrait studio, lecture hall, as well as new exhibition and performance spaces for artists. The university has reached out to community partners to collaborate on the project.[15] L+M Development partnering with Prudential and Goldman Sachs broke ground in June 2015.[16] The building has 60% dedicated market rate housing units and 40% affordable units[7] to promote the healthy revitalization of Newark while serving those who already live in Newark. The atrium featuring a grand staircase is capped by a steel-and-glass skylight and serves as the focal point for the redevelopment.[7] The complex also has a CityMD urgent care doctors office, Barnes & Noble bookstore, an upscale restaurant opened by celebrity chef Marcus Samuelson, and other businesses including a Sweetwaters Coffee, an Indian restaurant called Curry Up, an upscale wines and liquor establishment called Cool Vines, and an Industrial Bank branch.[17] The building reopened in January 2017.[18]
