While the Endowment holds over $3.69million in funds the Foundation seeks to raise a further $3.31million to reach a total goal of $7million to ensure the ISS can be continue in perpetuity allowing for rising costs over the years. The Foundation seeks to do this via donations, grants and bequests. The Messel Endowment is open to accept donations at any time and currently has over 200 supporters — all of whom the Foundation is highly appreciative and values greatly. Donations of $2.00 and over are tax-deductible. Pledged gifts i.e. donations spread over a three to five year period are also accepted and are tax deductible. The ISS now has over 4,000 alumni with many going onto outstanding achievements in their chosen fields including science, medicine, engineering and technology. The ISS honours excellence in our high-achieving youth and encourages them to reach their full potential and pursue careers in science and its related areas. A donation to the Messel Endowment is really an investment in the future of these young scientists. A donation form can be found at the back of this book and at www.physics.usyd.edu. au/foundation 4 LIGHT & MATTER MESSEL ENDOWMENT DONATION HONOUR BOARD The Science Foundation for Physics established the Messel Endowment in 1999 to honour Emeritus Professor Harry Messel AC CBE and to ensure the Professor Harry Messel International Science School, established in 1962 continues in perpetuity. The Endowment is managed to preserve the real value of all donations received. To date approximately $3.69 million has been raised. A list of donors who have donated $10,000 or more appears below. All donors to the Endowment are listed on the Messel Endowment Honour Banner in the Slade Lecture Theatre, School of Physics and can be viewed online at: www.physics.usyd.edu.au/foundation/ donations/MEhonour.shtml The Science Foundation for Physics appreciates and thanks all our Messel Endowment donors.
