Steile Futura halbfett (Medium) was released in 1952. Various styles were added until the mager (Light) weight in 1957. [Reichardt] The family was known as Bauer Topic in UK/US, Vox in Spain, and Zénith in France. It was designed by Paul Renner but is not related to his Futura. The name was likely a marketing decision. Round-formed alternates (a la Futura Display) were available for ‘A E K M N W’.
Digitally available as Steile Futura BQ (Berthold; Bold and Bold Italic, used for the sample) and as URW Topic (URW; Medium and Bold, each with italics). Tasse (Font Bureau; 4 weights in 5 widths) is a reinterpretation and expansion.
