The work of Emil Heitz (1892--1965) laid one of the keystones of cytogenetics. Using a new in situ method, he established between 1928 and 1935 the longitudinal differentiation of chromosomes in euchromatin (genetically active) and heterochromatin (genetically inert). He recognized the association of satellited chromosomes with the formation of the nucleolus, co-discovered the giant salivary chromosomes of diptera, and arrived at a cytological and genetic concept of chromosome structure that has been found essentially correct to date. Yet, Emil Heitz did not gain due recognition by his contemporaries, suffered from the political disturbances of his time, and spent almost a lifetime in isolation, bolstered only by the conviction that his scientific work was significant.
埃米尔·海茨（1892 - 1965）的工作为细胞遗传学奠定了基石之一。他采用一种新的原位方法，在1928年至1935年间确定了常染色质（基因活跃）和异染色质（基因惰性）中染色体的纵向分化。他认识到带有随体的染色体与核仁形成的关联，共同发现了双翅目昆虫的巨大唾液腺染色体，并得出了一种至今仍被认为基本正确的染色体结构的细胞学和遗传学概念。然而，埃米尔·海茨并未得到同时代人的应有认可，遭受了他那个时代政治动荡的影响，几乎一生都处于孤立状态，仅靠坚信自己的科学工作具有重要意义来支撑。
