In November 1926 Einstein wrote in support of Kaluza to try to impress upon people that he was a mathematician who had produced a remarkably novel idea and was worth far more than the position of Privatdozent which he still occupied.
Sa Nobyembre 1926 Einstein wrote sa suporta ng Kaluza na subukan na-ukit sa mga tao na siya ay isang dalub-agbilang na ginawa ng isang napaka nobela ideya at noon ay nagkakahalaga ng mas malayo kaysa sa posisyon ng Privatdozent na kung saan siya pa rin ginagamit.
