Research grants are available to established scientists of all ages working at accredited institutions in the United States. Applications will be judged on the scientific merit and the innovative aspects of the proposal as well as on the competence of the applicant. Research grants of up to three years will be provided. A renewal grant with a maximum of two years is possible, but it will be awarded on a competitive basis. Research grants will not be awarded to investigators who have already received, or expect to receive, substantial support from other sources, even if it is for an unrelated purpose. Application deadlines are June 1, September 1, and February 15 for the summer, fall, and spring sessions, respectively. The Foundation encourages the use of electronic mail. All correspondence and reports should be sent to email@whitehall.org. The Letter of Intent must be submitted in hard copy on institutional letterhead.
