Both the worlds of art and diversity are run predominantly by straight white men, and a few organizations like Out in Tech are trying to do something about it by promoting diversity in the world of tech.

That night, Out in Tech announced a new initiative that connects LGBTQ+ youth, particularly those who are people of color, to internships in the tech world. I asked George Wells, the COO of Lehmann Maupin board member of Out in Tech, about the problem with diversity in the worlds of art and tech, and what can be done to facilitate change.

Since its founding by Rachel Lehmann and David Maupin in 1996, Lehmann Maupin has been known for championing the work of groundbreaking artists like Teresita Fernández, Do Ho Suh, Mickalene Thomas and Nari Ward. Now, the New York gallery (which also has outposts in Hong Kong and Seoul) has opened a new three-story space in Chelsea.
Rachel Lehmann and David Maupin founded their gallery Lehmann Maupin in 1996 with a storefront in New York’s SoHo neighborhood. Since then, Lehmann Maupin has turned into a global art powerhouse with locations in New York, Hong Kong, and Seoul, showing artists like Mickalene Thomas, OSGEMEOS, McArthur Binion, Catherine Opie, Gilbert & George, Teresita Fernandez, Juergen Teller, and more. The duo recently expanded to a massive 8,500-square-foot, three-story flagship in Chelsea where a Getty Gas Station once stood, in the new Peter Marino-designed Getty building. An exhibition by Liza Lou served as the gallery’s inaugural show, featuring intricate beaded wall hangings made in part by women in South Africa. Lou would then explore the materiality of the beaded panels by smashing and destroying them to create textured patterns within the work. I quizzed Lehmann and Maupin about the strategy behind selecting the space, how they planned its design, diversity in the art world, and what’s next for the global gallery.
With almost every inch of New York’s West Chelsea neighbourhood now claimed, an exciting new residentialbuilding has sprouted up where the iconic Getty gas station once stood. Designed by Peter Marino, The Getty is comprised of six apartments – five full floor units and a single duplex penthouse with a roof terrace and private pool – and houses the Hill Art Foundation and the latest outpost of the Lehmann Maupin art gallery on the first four floors
Two days before its official opening, Lehmann Maupin’s Chelsea gallery is already teeming with visitors. Artists, employees, and friends are either prepping the space for the onslaught of attention soon to follow or admiring the newly installed works, which play with light and shadow on the ivory walls. One visitor is Liza Lou, the L.A.-based artist who works primarily with glass and beads and whose solo show will open the gallery later in the week. With a quiet confidence, Lou walks among her intricate creations lining the double-height space, her eyes bright.
For two decades, Lehmann Maupin has championed some of contemporary art’s most beloved luminaries, such as Do Ho Suh, Juergen Teller, and Mickalene Thomas. Founded by Rachel Lehmann and David Maupin in 1996, the gallery has had multiple homes around New York, as well as one in Hong Kong and another in Seoul to match its growing profile. Now it occupies the former site of the Getty—gas station, that is—which was an indelible landmark in New York’s Chelsea neighborhood. As of early September, Lehmann Maupin’s space is in a mixed-use residential building developed by the Victor Group, fittingly dubbed the Getty.
Lehmann Maupin is pleased to announce Liza Lou: The Classification and Nomenclature of Clouds as the inaugural exhibition of the gallery’s new, additional location at West 24th Street and Tenth Avenue. Lou will present a series of recent bodies of work produced over the last three years, including her monumental The Clouds (2015-18), recently exhibited at the 21st Biennale of Sydney. The gallery will host an opening reception for the artist on Thursday, September 6, from 6 to 8 PM, at 501 West 24th Street.
Lehmann Maupin is pleased to announce its representation of The Heidi Bucher Estate. Heidi Bucher was a Swiss artist best known for her innovative use of latex and her exploration of the physical boundaries between the body and our surroundings. Bucher’s practice can be considered an intricate process of historical preservation and metaphorical molting, which results in the poetic visualization of the complex relationship humans have with their bodies, their past, and the spaces they inhabit. Through this intensive investigation into the female body and domestic spaces, Bucher’s work seamlessly integrated two contemporaneous themes artists were grappling with during the 1970s and 1980s: the architecture of public and private spaces, and issues of femininity and the body.
Lehmann Maupin is pleased to announce its representation of Cecilia Vicuña. The multidisciplinary Chilean artist’s work addresses critical issues of the modern era—ecological destruction, feminism, human rights, and cultural homogenization—through her genre-bending projects uniting poetry, performance, painting, and site-specific installations that span more than 40 years. Vicuña lives and works in New York and Chile. Vicuña’s inaugural exhibition with the gallery will open May 19 at 536 West 22nd Street. A joint project with the artist is planned for the Brooklyn Museum and the Museum of Fine Arts, Boston, in the spring and fall of 2018.
Lehmann Maupin is pleased to announce that Shasha Tittmann has joined the gallery as a director in Hong Kong. Tittmann, who brings years of experience and is fluent in Mandarin and English, will manage the Hong Kong gallery starting in September, and focus on working with collectors and institutions in Asia. She has held positions at Tang Contemporary Art, Hong Kong and Beijing; and Opera Gallery, Hong Kong. Tittmann earned a Bachelor of Arts in art history from McGill University in Montreal, Canada.
