All else was extraneous

From John M. Barry, The Great Influenza, page 157. Describing one of the key scientific investigators of influenza, Oswald Avery, who manifests the discipline and focus that is so often associated with great achievements.

Avery had almost no personal life. He fled from one. He almost never entertained and rarely went out to dinner. Although he was close to and felt responsible for his younger brother and an orphaned cousin, his life, his world, was his research. All else was extraneous. Once the editor of a scientific journal asked him to write a memorial piece about Nobel laureate Karl Landsteiner, with whom he had worked closely at Rockefeller. In it Avery said nothing whatsoever about Landsteiner's personal life. The editor asked him to insert some personal details. Avery refused, stating that personal information would help the reader understand nothing that mattered, neither Landsteiner's achievements nor his thought processes.

(Landsteiner likely would have approved Avery's treatment. When he was notified he'd won the Nobel Prize, he continued working in his laboratory all day, got home so late that his wife was asleep, and did not wake her to give her the news.)
