Daniel R. Altschuler (born 1944 in Montevideo) is a Uruguayan physicist linked in his professional activity to the Arecibo radio telescope in Puerto Rico, where he was director from 1992 to 2003.^[1] He is a writer, known for his science outreach work, and is very sensitive to the distinction between science and pseudoscience. In 2010 he received the Andrew Gemant Award from the American Institute of Physics.^[2]

Daniel Altschuler was born in Montevideo, Uruguay, the son of German immigrants. He grew up speaking German at home and Spanish in the street. He entered the Faculty of Engineering at the Universidad de la República in Uruguay and then obtained a scholarship to continue studies at Duke University in Durham, North Carolina, where he earned his bachelor's degree in engineering.

He arrived in Puerto Rico in 1979 and entered the faculty of the Inter-American University in San Germán. In 1981 he was appointed professor in the Department of Physics at the University of Puerto Rico in Río Piedras, San Juan. In 1989 he was invited to work at the Arecibo Radio Telescope,^[3] and in 1991 he was appointed director of that institution, a position he held until 2003. He then headed the Observatory’s office for scientific outreach.

He completed his graduate studies at Brandeis University in Waltham, Massachusetts, where he earned a doctorate in physics, after which he did postgraduate studies at the University of Maryland. His research relates to quasars and hydrogen in galaxies.

His concern about the lack of scientific knowledge across a large sector of the public, and his great interest in scientific dissemination, has motivated him to give conferences and talks across the globe (e.g. Madrid, Johannesburg, Montevideo).

He is Professor of Physics at the University of Puerto Rico in Río Piedras.

In 2010 he received the Andrew Gemant Award from the American Institute of Physics for his contribution to science education.^[2]
