While in that position, he was also active in a leading role in the ICRC, traveling to Germany several times to negotiate for better treatment of civilians and prisoners, in part using the contacts gained during his two years as High Commissioner in Danzig.
任职期间，他还活跃于红十字国际委员会，发挥主导作用，多次去往德国进行交涉，为平民和战俘争取更好的待遇，部分地应用到了他在但泽担任高级专员的两年中积累的关系网。
