American Securities (1947 family office → private equity since 1994)

New York–based middle/upper-middle-market private equity firm with roots as the Rosenwald family office (heirs of Sears, Roebuck's Julius Rosenwald). Since converting to a third-party private equity model in 1994, it has focused on industrials, specialty chemicals and materials, building products, healthcare services and business services, supported by an in-house operating "Resources Group." Flagship American Securities Partners VIII closed at its $7.0bn hard cap in 2018. Its record spans big wins (Foundation Building Materials → Lowe's at ~$8.8bn; MPG → American Axle at ~$3.3bn) and high-profile failures (Air Methods' 2023 bankruptcy; regulatory overhang at prison-phone provider GTL/ViaPath).
