Homer F. DaBoll Award

Homer F. DaBoll was born on May 22, 1920. He led numerous grazing occultation expeditions in the Chicago area spanning 3 decades, from the 1960’s to 1990. He was the first ever editor of Occultation Newsletter for 16 years from its first issue in 1974 thru early 1990 when health reasons forced him to pass on the Editorial duties to Dr. Joan Dunham. DaBoll was the person who came up with the acronym IOTA, International Occultation Timing Association. Members of IOTA have always held Homer DaBoll in the highest regard for his numerous contributions to occultation observations, expeditions, ON, and his many other volunteer efforts. Homer DaBoll passed away in March 10, 1990 in Saint Charles, Illinois at the age of 69.

The Homer F. DaBoll Award is given to recognize significant contributions to the field of occultation science and to the work of IOTA.

David E. Laird Award

David E. Laird, born in 1931, was a physics teacher in Cincinnati, Ohio.  He organized grazing occultation expeditions throughout the Mid-West starting in the 1960's.  In October, 1966, he published articles in "Have Telescope: Will Travel".  He confirmed the existence of a large impact crater on the lunar far side. David suffered from leukemia and died in 1968 at the age of 31.

The David E. Laird Award is given to recognize those who, more than 15 years ago, made significant contributions to occultation science and to the work of the IOTA.

IOTA Lifetime Achievement Award

The IOTA Lifetime Achievement Award is given, as needed, to recognize outstanding contributions to the science of occultations and to the work of the International Occultation and Timing Association over an extended period of the recipient's lifetime.

The IOTA Award Committee accepts nominations from IOTA individuals worldwide for the award.

Award nominations are solicited in early June of each year.

Present Committee members include: Terrence Redding (chair), Robert Buchheim, Colin Haig, and all previous award winners.

The Committee’s main objective in selecting an award recipient is to reach a consensus and not choosing someone by a majority vote.

The rules allow any person to be considered for the award except for current IOTA Officers and Committee members. 

Each year’s presentations of the annual awards are made by the Award Committee Chair at the IOTA Annual Meeting.

In the event a Lifetime Achievement Award is also given, it will be presented at that time as well.
