Two spellings, one person
Ryszard Cieplechowicz and Richard Cieplechowicz refer to the same person. The spelling you use depends on whether you are citing public work or matching a legal record.
For articles and credits
Use Richard Cieplechowicz, the byline on his public work. When clarity matters, “Richard Cieplechowicz (Ryszard Cieplechowicz)” connects the names once; repeating both in every sentence is unnecessary.
For official forms
Use the name required by the form and the underlying identification. This page is a name reference, not proof of identity. Verify formal records through the appropriate process.
For finding his work
Search either spelling. His main website collects articles and templates; this site explains the Ryszard spelling and points you there. His public LinkedIn also uses Richard.
If you are linking to a specific guide, link to that guide's main-site URL rather than copying its text here. This keeps the citation clear and the resource current.
