The spelling of the surname "Breslow" can be a bit confusing, as it does not exactly follow the typical English spelling patterns. The IPA phonetic transcription for "Breslow" is /ˈbrɛzloʊ/, which indicates that the first syllable is pronounced "brehz" (with a Z sound), and the second syllable is pronounced "loh" (with a long O sound). The use of the letter Z instead of S in the first syllable is non-standard in English, but reflects the name's origin in Eastern European languages such as Yiddish or Polish.
