ויאמר ראובן אל אביו לאמר את שני בני תמית
Maran Harav A.Y.L. Shteinman zt"l said he heard that Reb Chaim Brisker would not add his father's name (בן הגרי"ד) when signing his name.
The reason is because the first year after the death of a parent or Rebbie one is obligated to add הריני כפרת משכבו when mentioning their name.
(as if to say that all sins of the parent/Rebbie should be transferred to the child/Talmid.
It is true that the Halacha requires you to add הכ"מ but if you don't mention the father there won't be a need
to add הכ"מ.
Reb Chaim was concerned and fearful of accepting the sins of his father the Bais Halevi. Since he didn't mention himthe first year he kept it up and *never signed his name "בן הגרי"ד"
Harav Shteinman brings this story as one more proof that one can actually transfer sins from one person to another.
This is what Reuvain told his father that he is prepared to accept all the sins which might even cause the death
of his two sons should he not bring back Binyamin. (see Malbim)
Rav Shteinman writes some say that R. Chaim changed his mind later in life.
