The life of the blue eyed Henriette (Jetti) von Aigentler (1854-1938), the famous Boltzmann's wife was described. Jetti's mother was Slovene Enrika (Henrika) Fišer married von Aigentler (1828-1873) from Gorica and that fact is not widely known. Jetti studied hard because girls of her time had no free entrance into university lecture rooms. Jetti's achievement as a teacher and her contributions to her husband's success were discussed. To avoid his painful short sightedness, she read the scientific papers to her fiancée and helped in his correspondence. Her polite worldwide connections helped a great deal to her husband's scientific achievements and enabled his frequent changes of university chairs. Jetti never published any scientific papers under her own name, but she was in correspondence with the best minds of her era. She loved her older sister and her children Šantels, who eventually became famous Slovene painters. Jetti was unable to postpone the tragedy of her husband in Devin. She helped the success of her son-in-law Ludwig Flamm (1885 - 1964) and grandson Dieter Flamm in their physics research. We claimed that Boltzmann's wife connected him with Slovene nation even more than his Slovene teacher Jožef Stefan.
