    Very little is known of his childhood and adolescent years. However, it is known that Rapp learned the engineering profession and was employed by Züst automotive company from approx. 1908 to 1911. It is believed he was active as a technical designer with Daimler Benz until 1912. Rapp left Daimler-Benz to head a branch of Flugwerk Deutschland GmbH.

    Flugwerk Deutschland GmbH probably transferred its headquarters from Gelsenkirchen-Rotthausen to Brand near Aachen.The articles of association were ratified on February 15, 1912, and the entry in the Aachen Commercial Register was effected onMarch 5, 1912. The object of the business was the manufacture and sale of aircraft, the construction and sale of machinery and equipment in the areas of aircraft engineering and operation of airfields and aerodromes. On 20 May 1913, a branch was set up for aeroengine production at Schleissheimer Straße 288 (near the first airport on the Oberwiesenfeld) in Munich-Milbertshofen , and Karl Rapp and Joseph Wirth were given power of attorney in Munich. Rapp, working as an engineer and operations manager for the company, engaged in the construction of several biplanes and a monoplane. Rapp also designed aeroengines, one of which was the FD 1416 aeroengine. The company took participation in the General Air Show in Berlin in 1912. However, the company w...

    Karl Rapp and Julius Auspitzer founded Karl Rapp Motorenwerke GmbH with a capital stock of RM 200.000 the on 28 October 1913 on the site of Flugwerke Deutschland (after the company went into liquidation). General Consul Auspitzer was the company's sole shareholder, with the operational side of the company managed by Karl Rapp. The idea was for the new company to build and sell "engines of all types, in particular internal combustion engines for aircraft and motor vehicles", in addition to building an engine for the 2nd Kaiser's Trophy Competition, (but it was not ready in time). The company expanded rapidly and employed 370 coworkers by 1915. Several aircraft prototypes were designed in the Rapp Motorenwerke, but success eluded all these prototypes because of weaknesses in the design. At the beginning of the First World War, the company was one of the key Bavarian companies for the war effort, and appeared to have gained a certain reputation, despite the fact that none of the design...

    After Rapp left the company (immediately it was renamed BMW) he became chief engineer and head of the Aeroengine Department of the L.A. Riedlinger Machine Factory where he was probably employed until October 1923. Rapp lived in Switzerland from 1934, running a small observatory making solar observations. Karl Friedrich Rapp died in 1962 in Locarno.

    Karl Rapp and Julius Aus­pitzer founded the Rapp Mo­toren­werke GmbH on 27 Oc­to­ber 1913 with a cap­i­tal stock of RM 200,000. The com­pany was es­tab­lished in Mil­bertshofen on the for­mer site of the Mu­nich branch of Flug­w­erk Deutsch­land GmbH, a firm at which Karl Rapp had held a lead­ing po­si­tion and that had gone into liq­ui­da­tion in the sum­mer of 1913.Gen­eral Con­sul Aus­pitzer was the com­pany's sole share­holder, with the op­er­a­tional side of the com­pany man­aged by Karl Rapp. The com­pany's stated pur­pose was to build and sell "en­gines of all types, in par­tic­u­lar in­ter­nal com­bus­tion en­gines for air­craft and motor ve­hi­cles". With the ac­qui­si­tion of Flug­w­erk Deutsch­land, the com­pany had also taken over the four-cylin­der en­gines that Karl Rapp had de­vel­oped there, and Rapp Mo­toren­werke im­me­di­ately started to offer these en­gines to the Pruss­ian mil­i­tary au­thor­i­ties as the Rapp 100 hp.While the 100 hp four-cylin­der en­gine was i...

    At the be­gin­ning of the First World War, the com­pany was one of the key Bavar­ian com­pa­nies for the war ef­fort and ap­peared to have gained a cer­tain rep­u­ta­tion, de­spite the fact that none of the de­signs and de­vel­op­ments achieved any real suc­cess.Since air­craft en­gine de­mand could not be met alone by the es­tab­lished com­pa­nies like Argus, Daim­ler and Benz, the Ger­man mil­i­tary au­thor­i­ties also placed or­ders for en­gines at the Rapp-Motorenwerke.With the in­flux of cap­i­tal, the com­pany ex­panded rapidly and em­ployed 370 work­ers by end of Sep­tem­ber 1915. The first de­liv­er­ies of Rapp en­gines how­ever were re­jected by the Pruss­ian Army Ad­min­is­tra­tion as un­suit­able, and so they re­frained from fur­ther orders.De­spite this, the Bavar­ian Army ad­min­is­tra­tion as well as the Ger­man Navy ad­min­is­tra­tion still kept or­der­ing Rapp en­gines in lim­ited amounts, and also the Aus­tro-Hun­gar­ian Army and the Aus­tro-Hun­gar­ian Navy ad­min­...

    On 20 May 1917, Rapp Mo­toren­werke reg­is­tered the doc­u­men­ta­tion for the con­struc­tion de­sign for the new en­gine, dubbed "type III". Friz' de­sign, (based on Karl Rapp's orig­i­nal de­sign) was laid out as an in-line six-cylin­der, which guar­an­teed op­ti­mum bal­ance, with few small vi­bra­tions. The en­gine was suc­cess­ful, but the real break­through came in 1917, when Friz in­te­grated a ba­si­cally sim­ple throt­tle but­ter­fly into the "high-al­ti­tude car­bu­ret­tor", en­abling the en­gine to de­velop its full power high above the ground. This is pre­cisely the rea­son why the en­gine, now dubbed "type IIIa", had unique su­pe­ri­or­ity in air com­bat. Franz-Zeno Diemer, the pi­o­neer­ing avi­a­tor and test pilot for the com­pany, sets a new world al­ti­tude record with a 32,000 ft (9,760 m) flight in 1919 fly­ing a DFW F 37/III (ex­per­i­men­tal two-seater, often re­ferred to as the C-IV) with a BMW Type IV air­craft en­gine. Sep­tem­ber of the same year, Diemer set...

    The de­ci­sion by the Pruss­ian Army Ad­min­is­tra­tion to order 600 units of the in­no­v­a­tive high-al­ti­tude aero­engine (pro­ject name "BBE") prompted re­or­ga­niz­ing the legal struc­ture of the com­pany. The aero­engine de­vel­oped by Friz had turned Rapp Mo­toren­werke into an es­sen­tial con­trib­u­tor to the war ef­fort vir­tu­ally overnight. From the mid­dle of 1917 on­ward, the busi­ness, which would prob­a­bly have dis­ap­peared from his­tory never to be heard of again, now en­joyed the un­di­vided at­ten­tion of the armed ser­vices and other gov­ern­men­tal bod­ies. Large sub­si­dies flowed in and the Mu­nich com­pany re­ceived well-fi­nanced pro­duc­tion or­ders. The recog­ni­tion that Max Friz gained with his en­gine made it clear to all the se­nior man­agers that, up to now, Karl Rapp and his in­ad­e­quate en­gine de­signs had held the com­pany back from suc­cess. In Friz, they now had an ex­cel­lent chief de­signer on hand and were no longer de­pen­dent on Rapp. Th...
