According to William Denke, Jr "H-bar" (1969)

The derivation for permittivity of free space (e0) discovered by
William Herman Denke, Jr (my uncle)

Derivation: e0

e0=(e^4)u0/(hbar^2)

e0=(1.602176531 x 10^-19 A-s)^4)(1.256637061... x 10^-6
kg-m-sr/A^2-s^2)/(9.670552783 x 10^-36 kg-m^2-sr/s)^2
e0=(6.589333151 x 10^-76 A^4-s^4)(1.256637061... x 10^-6
kg-m-sr/A^2-s^2)/(9.351959113 x 10^-71 kg^2-m^4-sr^2/s^2)
e0=(8.280400244 x 10^-82 kg-m-sr-A^2-s^2)/(9.351959113 x 10^-71
kg^2-m^4-sr^2/s^2)
e0=8.854187817... x 10^-12 A^2-s^4/kg-m^3-sr

The derivation for permeability of free space (u0) discovered by
William Herman Denke, III (my cousin)

Derivation: u0

u0=(hbar^2)e0/(e^4)

u0=(9.670552783 x 10^-36 kg-m^2-sr/s)^2)(8.854187817... x 10^-12

It was my greatgrandfather who discovered this equation in 1888

e=[(hbar^2)e0/u0]^1/4
hbar=[(e^4)u0/e0]^1/2
e0=(e^4)u0/(hbar^2)
u0=(hbar^2)e0/(e^4)
