Father of Sergio Lanza was an Italian seller of Remington typewriters. When, in '20s' he seen first Olivetti machines, he wrote to Camillo Olivetti suggesting some improvements. They become friends, Mr. Lanza become an Olivetti representative and the young Sergio was asked to reach Ivrea and to work in Olivetti. Due to family problems Sergio gave up this opportunity.

Sergio Lanza registered several patents related to mechanical devices and founded the Brevetti Lanza company. In Italian brevetti means patents.
Production of adding machines ended when Lanza's patented Addipresto was copied by cheaper machines made in Hong Kong (Swift Handy Calculator, Bentley, Schnellrechner (Maschine). Indeed Lanza patented his machines only in Italy.

An interesting patent by Lanza (Patent:IT488565) concerns a device for the setting of the multiplier into electrical adding or calculating machines. It was conceived in two versions. First version is identical to multiplier buit-in some Everest machines (e.g. Multarapid) and M4). Then we can suppose that Everest worked under Lanza's license. Second version was added by resellers (not in factory) to machines of other companies (e.g. Totalia or Monroe MA).
