It’s not possible to tell from your snippet “who published linguistic findings that showed …” because the key part after the ellipsis is missing, and there are many famous “linguistic findings” that could fit.

To give a sense of why this is ambiguous, here are a few classic cases people often ask about:

  • Experiments on linguistic relativity (how language influences thought) were famously reported by researchers working in the mid‑20th century, whose results on language and perception were published in the 1950s.
  • Anthropological work connecting language and culture very closely is strongly associated with Franz Boas, Edward Sapir, and later Daniel Everett, who published widely on how culture shapes language structure and use.

Because many different teams and authors have “published linguistic findings that showed X” (effects on memory, color perception, spatial reasoning, cultural patterns, etc.), I can’t reliably identify the specific person or paper without more detail.

To avoid giving you a wrong name, I need at least one of these:

  • The rest of the sentence after “showed …” (for example, “… showed that language influences color perception”).
  • A hint about the topic (e.g., color words, gendered nouns, Pirahã, language and culture, child language, brain imaging).
  • Rough time period or context (e.g., “1950s American psychologists,” “recent fMRI study across many languages,” “Amazonian field linguist”).

If you can paste the full original sentence or describe what those findings “showed,” I can narrow it down and give you a precise answer instead of guessing.
