I found it - in case someone else needs it:

Sub MoveUniqueNamesHorizontally()
Dim X As Long
Dim Z As Long
Dim UniqueNames As String
UniqueNames = "*"
Z = 1
With Worksheets("Sheet1")
For X = 1 To .Cells(.Rows.Count, "A").End(xlUp).Row
If InStr(UniqueNames, "*" & .Cells(X, "A").Value & "*") = 0 Then
UniqueNames = UniqueNames & .Cells(X, "A").Value & "*"
Worksheets("Sheet2").Cells(1, Z).Value = .Cells(X, "A").Value
Z = Z + 1
End If
Next
End With
End Sub


Sub MoveUniqueNamesVertically()
Dim X As Long
Dim Z As Long
Dim UniqueNames As String
UniqueNames = "*"
Z = 1
With Worksheets("Sheet1")
For X = 1 To .Cells(.Rows.Count, "A").End(xlUp).Row
If InStr(UniqueNames, "*" & .Cells(X, "A").Value & "*") = 0 Then
UniqueNames = UniqueNames & .Cells(X, "A").Value & "*"
Worksheets("Sheet2").Cells(Z, "A").Value = .Cells(X,
"A").Value
Z = Z + 1
End If
Next
End With
End Sub

Many thanks Rick.
