How to Write a Biography: A Step-by-Step Guide

Need to turn life facts into a page-turning story? Follow this 7-step guide to writing a compelling biography—plus see how Merlin AI can brainstorm, fact-check, and polish every paragraph for you.

I used to think a biography was just “name, date, accomplishment, repeat.” My first attempt—about my great-grandmother—felt like a timeline on life support.

After workshopping dozens of bios for family, nonprofits, and podcasts, I finally cracked a formula that puts story ahead of statistics.

Below are seven practical steps you can copy for a short blog profile or a full-length book.

I’ll point out exactly where Merlin AI can jump in to save time, spark ideas, and catch sneaky typos.

Why Biographies Matter

  • Legacy: They preserve memories past the social-media scroll.
  • Inspiration: A well-told life shows readers what’s possible.
  • Context: Biographies stitch personal moments into larger history.

Spending an hour on a clear structure now beats stitching dates together at midnight later.

Step 1 Pin Down Purpose, Audience, and Scope

  • Purpose: Tribute? School assignment? Magazine feature?
  • Audience: Family, scholars, casual readers, or industry insiders?
  • Scope: From birth to obituary or just a pivotal decade?

Write these choices on a sticky note—every later decision should echo them.

Quick Merlin Move Paste your idea into Merlin and ask: “Summarize purpose, audience, and ideal length for this biography in 50 words.” Now you’ve got a North Star for the whole project.

Step 2 Gather Sources Like a Detective

Source TypeExamplesWhy It Matters
PrimaryLetters, interviews, journals, photosFirst-hand authenticity
SecondaryBooks, articles, documentariesContext & fact-checking
Public RecordsBirth certificates, patents, military filesDates and spellings you can prove

Spend 30 minutes mapping what you need and where you’ll find it—future-you will thank you.

Quick Merlin Move Prompt: “Make a 12-item source checklist for a 5,000-word biography of a 1990s tech founder.” Copy the list into your research doc and start ticking boxes.

Step 3 Sketch the Narrative Arc (Hero’s-Journey Lite)

Even factual lives follow story beats. Draft a one-page outline using these sections:

  • Early Roots & Influences
  • Inciting Spark – the event that set their path
  • Rising Challenges & Breakthroughs
  • Pivotal Moment / Peak
  • Setbacks, Failures, or Scandals
  • Legacy & Impact

Aim for three bullet incidents per section.> Outlining now tames rabbit-holes later.

Step 4 Hook Readers with a Cinematic Opening

Skip the birth certificate; open mid-action:

“On a muggy July evening in 1987, twelve-year-old Luis Torres rigged a car battery to power a beat-up IBM PC—and booted his first line of code.”

Then zoom out for a two-sentence overview—who, what, and why this life matters.

Quick Merlin Move Prompt: “Write three 35-word cinematic opening lines about a young inventor fixing a computer with a car battery.” Pick the one that gives you chills, tune wording, and go.

Step 5 – Write Scene-Driven Chapters

Show, Don’t Tell

ToolHow to UseTiny Example
Dialogue snippetsPull from letters/interviews“‘Give me five volts and I’ll change the world,’ Luis joked.”
Sensory detailsSound, smell, texture“Solder smoke curled through the garage like incense.”
Mini-scene stakesOne conflict per sceneMissed payroll, patent race, public failure

Aim for at least one 100-word vignette per chapter that shows character through action.

Quick Merlin Move Feed Merlin a bullet—e.g. “first big product pitch disaster”—and prompt: “Expand into an 80-word scene with tension and dialogue.” Adjust to match your voice and verified facts.

Step 6 – Blend Facts, Context, and Reflection

A Solid Chapter Rhythm:

  1. Narrative scene (feel present)
  2. Context paragraph (history, market, culture)
  3. Reflection/analysis (what this meant for the subject and others)

Keep roughly a 40-40-20 split so readers stay engaged and informed.

Fact-Check on the Fly Prompt: “Verify the price of a 1993 IBM ThinkPad (primary source link).” Paste the citation right into your draft.

Step 7 Land a Resonant Conclusion

Circle back to the opener and spotlight impact:

“Thirty years after hot-wiring that IBM, Luis’s open-source batteries power off-grid clinics from Lima to Lagos—proof that curiosity, not circumstance, builds futures.”

Close with a takeaway or forward look—awards, philanthropy, influence on today’s innovators.

FAQ

How long should my bio be?

  • Short blog: 800–1,200 words
  • Book proposal: 60,000–90,000 words

Match audience expectations.

Can I recreate dialogue? Only from confirmed interviews or letters. Otherwise, use indirect speech:

He told friends he’d “never sell.”

How do I cover flaws or scandals? Include them factually with sources; balanced portraits build trust.
