of atomic-structure calculations. The early version of the MCHF program, published in the first volume of Computer Physics Communications received two Citation Classics Awards in 1987. She authored an influential monograph on Hartree-Fock approaches to the first-principles calculation of atomic structure, and coauthored a substantial successor work. One of her largest efforts in the field is the calculation of the complete lower spectra of the beryllium-like to argon-like isoelectronic sequences, amounting to the publication of data covering 400 journal pages and a total of over 150 ions. She also authored a scientific biography of her Ph.D. thesis advisor, Douglas Hartree. Froese Fischer is currently an emerita research professor of computer science at Vanderbilt University and a Guest Scientist in the Atomic Spectroscopy Group at NIST. She is the widow of Patrick C. Fischer, himself a noted computer scientist and former professor at Vanderbilt. An autobiographical account of her own life up to the year 2000 was published in Molecular Physics, and a biographical review of her scientific work up to 2019 has been published in Atoms.
