Was Isidor Straus's wife with him on the Titanic?

yes she was...her name was ida straus and she stayed with him until the boat sank even though she was allowed to get on the life boats. But when Mr. Woolner tried to get Ida Straus onto one of the last life boats she refused saying, "We have been living together for many years, and where you go, I go." After she said that Mr. Woolner said to Isidor, "I am sure nobody would object to an old gentleman like you getting in. There seems to be room in this boat." But Isidor objected saying, "I will not go before the other men."
