One Fund's Kenneth Feinberg

The One Fund has amassed $30 million to help compensate the victims of the Boston Marathon bombing and by the end of June, it will be in their hands.

Today, we learned just how that money will be distributed. Top priority is for those who lost family members in the attack, followed by double amputees, those suffering from brain damage, then single amputees.

The man behind that calculation is Kenneth Feinberg, a lawyer in Washington, D.C. who has been putting a price on pain for decades. He's been in charge of funds compensating Vietnam veterans exposed to Agent Orange, survivors of 9-11, victims of the shooting at Virginia Tech. The list goes on... and on.

Kenneth Feinberg, administrator of the One Fund.

Boston Globe "A fund to benefit victims of the Boston ­Marathon bombings will distribute payments to people treated as outpatients, in addition to those hospitalized and to families of those killed, accord­ing to final rules issued Wednesday for distributing the money."

NBC News "Blunt yet sympathetic. Good with a calculator under pressure. Loves doing pro-bono work as a hobby. Because of all of those attributes, arbitration attorney Kenneth Feinberg is asked again and again to take on the awful task of putting price tags on pain, suffering and even human life."
