2 Neutrinos in icecap ? 1988: Ed Zeller (Kansas)  Francis John Learned

3 1988: Pomerantz workshop, NSF Science and Technology Center for the South Pole (Andrew Westphal, Tim Miller, Doug Lowder, Buford Price) 1989: attempt of Westphal and Lowder to measure ice transparency in existing boreholes Jan. 89, ICRC, Adelaide: Decide to propose Amanda ( Buford Price, Doug Lowder, Steve Barwick, Bob Morse, Francis Halzen, Alan Watson)

80 What was your happiest event with AMANDA ?

81 String 1 deployed ! (January 9, 1996)

82 What was your most tantalizing event with AMANDA?
