Alfred Adler had two problem Sigmunds in his life. Best known is Freud, but preceding that he had 'issues' with his older brother Sigmund, described as "intelligent, competent, and domineering". Adler apparently felt "eclipsed by his 'model brother' and resented his favored status in the family" (Hoffman, 1994, p. 11). In latter years, Sigmund Adler helped his siblings financially, including Alfred. This support prompted the world-famous, middle-aged Alfred Adler to refer to his older brother as "a good industrious fellow [who] was always ahead of me—is still ahead of me" (Bottome, 1957, p. 27).
Sigmund Freud had a fair few siblings, but the one who stayed home and looked after the parents was his sister, Esther Adolfine (Dolfi). Unmarried, she cared first for her father Jakob when he fell ill, then her mother, becoming 'impetuous' Amalie's constant companion, which her nephew Martin considered could not have been a welcome fate. "She was not clever or in any way remarkable, and it might be true to say that constant attendance on Amalie had suppressed her personality into a condition of dependence from which she never recovered" (M. Freud, 1958, p. 16).
Sigmund was no doubt grateful as the following letter suggests:
July 22, 1930
The enclosed is just some pocket money for your birthday for which I send you my best wishes as well as my most heartfelt gratitude for your invaluable services throughout all these years. As you know, we shall be in Mother's immediate neighborhood this summer, but unfortunately I don't yet know when.
